Not really un-expected...
When any company sais a date, it's a drop-dead date. They specified that September would not be considered late, so holding delivery till the end of Sept is what I pretty much expected from the beginning.
Now, that said, if they do push to Oct, then I would be all over them like a cat on spilt milk. I would be raising all kinds of hell if they can't deliver in Sept, and demanding some sort of recompense or I would be blasting to all the world about their late deliveries and un-reliable business.
But, that's in the future, for now ill hold off and expect them to keep their end of the deal.

Here we go. So no talk of August. Now delivery is September. With late being end of October? No miners but are NOW build a sample miner. Hope for the best but expect the worst.

I'd prob go ideal case and then best case/worst case and then a bottom line/absolute worst case scenario. At least it would give me a feel for what's happening.

Not trying to ruffle any feathers, but any "Do The Math" computation has 2 big assumptions, which can be manipulated any way the person sees fit.

1) Difficulty increase rate.
2) Market price for the coin.

No matter how much you try to hold tight to the numbers, these 2 variables can wreak havoc with your calculations.

Why is the miner cost $3,995?

That Bitfinex debaucle basically handed BTC a $70 haircut, at today's price, from which it has yet to grow out.  Cruel mistress she is.

Well no matter how you look at it we need a price pump in BTC to say $700 bucks *mario* and good old Yoshi ..that is LTC at around 5-6 bucks...no matter what your equip
or how you look at it.......

I'll probably still do a little bit more then break even on the new hoard..but where is the fun in that? At around $4 that is......sigh....

crypto you merciless bitch

Now we know why there isn't a video - there isn't a production version of the miner and is still in development.  The good news is the upcoming test batch of sample miners will most likely yield some pictures!  

Here's the math. About $2.67/day  for 110MH A2.

A dyingTitan, with dies turned off, running at 110MH would consume about 400w at the wall would return $3.49/day

Do the math.

 at 1200 Mhz "full turbo" clock in the original software, I've got A2 units turning about 110 MH eating about 1250 watts at the wall.

 I'm not at "under 3c/KWH", closer to 4 where I'm at - but hopefully I'll be able to do a LOCAL move into one of the under-3c/KWH adjacent counties sometime in the next year or so - it's MUCH easier to find a place when you're LOCAL after all.


 As long as Litecoin pricing stays in the same ballpark $4 price it's been most of the last year+ (I'm ignoring the short spike to $5), A2s will remain profitable even if the hashrate doubles as long as you have low-enough cost electric.

 In my case, my A2 units are already pretty much paid off so ROI isn't going to be an issue - even if I DON'T recycle all of the PS in them.

Update from Chloe:

I asked if shipping could be paid in BTC.

Response:
We prefer wire payment. Your delivery will be in September according to current pre-order status. We are now making sample miners for a test.

you could be right thou I think a lot of A2's are still being run in china and alcheminer 256 with their 3rd party firmware seems successful  but just the other day someone with 3c kwh
in texas says he was still running A2's at a profit

but China has a lot of data hall scrypt I've been told NON KNC or so the myth goes

but hey you could be right I just know KNC was trying to sell 5k of units..but cancelled last and 3rd batch...so why my hedge

main thing for me is with the improved (think V2 rocket vs NASA now) gen trakin firmware to monitor and the other mods i have done and such ..the Titans I have
are likely to have a lot less stress/temp in the next 2 years then the last 2 years....so looking good with all the 3rd party support..so assuming scrypt hangs together
in some manner (mainly LTC) we should be ok no matter if it is a Titan or an A4 (assuming they come out sometime before Oct ouch)

I've been in touch with a Chinese reseller of Innosilicon and they claim they will have stock at the end of the month.  They're not pressuring me for a pre-order, but are asking a USD$200 premium ($2000/unit) plus $150 to ship to the west coast of the US so hope springs eternal!

 Innosilicon claims that the MAJORITY of Scrypt hashing power comes from their A2 units.
 I have no reason to doubt that claim, given how COMMON A2 units are and how ROCK SOLID RELIABLE the A2 Terminator units have proven to be.

 TItans also have the well known issue that they commonly had cores or even entire dies DIE - even if KNC built a total of 5000 complete Titan miners, I doubt that the equivilent of 3500 full miners of them are still hashing today factoring in the DEAD CORE/DIE issue.


 The Gridseed GC3355 based gear was way down the list on efficiency (specifically including the GBlack blades) - the very few SFARDS SF100 units, the Titan, tossup between the A2 varients and the Alcheminer, some or all of the Zeus varients, the Silverfish, among others were ALL more efficient, though in some cases the relative efficiency was close.
 With that said, *IF YOUR ELECTRIC COST IN IN THE 3c/KWH range* the GC3355-based gear CAN still be profitable - BARELY - at current Litecoin difficulty/price.

 Your GBlack numbers sound reasonable to a hair low on efficiency - I was seeing 2.7 out of each side of the 80-blades at somewhere around 45 watts (some variation but tended to be small).


 If you used bitcoinwisdom to calculate profitability, DO keep in mind that they never updated the block reward for litecoin OR for scrypt, you have to enter in the correct number manually.

Also true. I just ran the numbers on a GBlack, if I remember right mine would hash at 23MHs and about 420 watts at the wall. This is showing as profitable at $0.08/KW which is not what I expected to see. It doesnt make much but it is in the green. Maybe they are still hashing away and I just didnt realize it.

At $0.05/KW a GBlack will bring in about $10 a month in profit.

The other factor is how cheap is the energy cost. If electricity costs you next to nothing then even the old stuff is still profitable.  But that is interesting what you pointed out regarding the numbers of possible rigs out there. 

You think thay only made 3500 titans? If you say the average titan hashes at 300mhs now, 300 x 3500 is just over 1000GHs. The network is currently at about 1600GHs. Where is the other 600Ghs coming from? Are there that many A2's still running? Anything else should be unprofitable Id think. If the average titan runs at 400mhs then that brings us to 1400GHs which could be right but I dont think most titans run at those speeds - I could be wrong tho.

5000 titans @ 300mhs is 1500GHs which also seems to closely fit.

I guess it depends on what older ASICs are still running. Last I did the math, gridseed GBlack's were no longer profitable and I think they were the third most efficient miner (A2 being 2nd and Titan 1st).

Im all for it if it helps keep costs down.

Wearing 6 hats, operating heavy equipment and electron microscopes while booking meetings... I can see it now! ROFL

I don't think it hurts to put out periodic requests for updates around the last week of Aug, but I wouldn't want to bug them too much.
