You must have seen this...
and yes I agree that gen 2 won't be earth shattering either.

Do you have a link for that? I asked for clarification in the BFL FAQ about the warranty, but given the current wording it sounds like if the Gen1 Single SC isn't produced anymore and it's past one year the warranty won't be honored.

ASIC Gen 2 isn't going to be like the transition from FPGA to ASIC; it's likely not going to be a mandatory upgrade.

I'd rather have 54Gh/s three weeks before BFL ships than 72Gh/s three weeks after 

Still, any potential hashrate bump is a good thing, and these would be profitable at 1 billion difficulty so 

At which point you'll get your warranty filled and you can trade it in for gen 2.

From the BFL FAQ...

I would say that you cannot count on a warranty of any longer than 1 year. There's a pretty decent chance we might be in ASIC gen 2 a year from when BFL ships, and there's no real point in continuing the existing line once the next gen is ready.

Giving a lifetime warranty on a highly overclocked chip would be quite a gamble IMO. And since BFL does give a lifetime warranty for the boards, they must be pretty sure it can run non-stop for at least a year.

I wouldn't mind if it takes 80 or 100 Watt instead of 60, if performance rises accordingly. It would still be on top.

Pulling from page 1, because this is exactly what I was told (I added bold emphasis)

Man this is good news for me, I really don't mind if it delays slightly again but I hope before 2013 arrives.
For me getting the ASICs before the 25 BTC drop was never really a concern, I simply love the idea of
helping to produce an economy that's much different than what is currently available in this world.  I
hope the enthusiasm with the currency can stay positive until the big mainstream adoption. 

I agree, they should just do a batch revision in the interim after shipping what they now have and then offer an upgrade for people who bought the 60. Maybe upgrade them to 80 or 90 and then resell the 60's to other customers as a separate SKU.

It would suck to get a rig and one month later end up with a dead chip(s). That would be pretty hard to fix and there would be almost no workaround for that. (RMA's and the confidence hit wouldn't be worth it)

Overclocking a video card that's $200 and you have a huge amount of previous overclocking information from other people at your disposal is one thing.  Overclocking a few thousand dollars ASIC rig that noone has any idea how it'll handle that short or long term is a whole different ballgame.

Increasing the clock speed is the surest way to lose their power efficency advantage.

I know.. weeks ago I got deleted on butterfly forums when I asked if they re-spin.. I'm an Engineer specialized in this field, I can understand, mostly, the big picture. 65nm and full custom asic is difficult for a small company.. difficulty can be described mathematically.. Ofc BFL can be plaint lucky, but from customer POV it is gambling despite what they say.. I need to cover one - two months of gap, I need to buy something, I will use my skill to discriminate..

Give it another week or 2, won't matter much for the delivery date of those I think. Only be quick once one of them starts delivering, hell will break loose.

The question is, is the company over confident in a good way or a bad way?

They might choose a route where they take a hit in profit to provide extra hardware.
They might choose a route where they over clock their chips to their maximum rating and thereby increase RMA returns in March. ($$$ lost)
They might choose a route where they give away relatively cheap nick knacks...but this is unlikely to make most customers happy.

They might choose to upgrade their second batch and have an upgrade program (very likely and is the cheaper option). (Aka the 30, 60, 90 program?)

They might choose to offer a second device to cover the difference. (Possible, but cost ineffective)

etc.

Talking big in an overconfident tone might keep their customers around. (That's what real Vendors do anyway!) It may also just as well signal that they have no painless plan in place and need to talk big to cover for that inability.

One guy on their forums is about to switch his investments from BFL to bASIC at a cost to BFL of 8,000 dollars.

BFL is also now deleting threads from customers with content which is not unexpected nor even offensive considering they invested in the company as a paying customer. I just left a thread open in my browser this morning  and refreshed it....poof, it is gone.

The censoring has apparently begun on their forums (IMO).

Man, I totally agree with you, except one point, I need to buy more ASIC, atleast for next month until I shift, its gamble right now, God knows I don't gamble..

We will find out, but after delivery probably, by firmware update or whatever is used for it. They just don't want anything to stand in the way of getting the asic out the door asap. What a merry-go-round we're in. The "in theory capable of 16Gh/s" comes from the article in Bitcoin Magazine nov. 4th edition.

I am a bit lazy to search the post where BFL state that their asic chip are already overclock and that there is still a bit room left for further overclocking.
I might search it tomorrow when I am not lazy anymore.

How much room? I thought they can go to 200% but people say they are already overclocked.

Actually, bfl under-clocks the chips, in theory they can run at 16Gh/s, but stability and life expectancy would suffer. Just as btcfpga said for their chips btw. There is room for overclocking for sure.
