BFL says Avalon is too "hot" and "irresponsible" in an eco friendly sort of way:
So I have been very focused on our ASIC launch for the past few weeks obviously and have not given a lot of thought towards the overall climate / state of ASICs until this evening, whilest rooting a new Nexus 7 GSM model (it's still got that new Android smell)...
A few things occurred to me, after giving them some thought and I am just throwing this out here:
bASIC
The lack of information from Tom (which was endemic from the start, but people had blinders on for a number of reasons), coupled with the little bit of information he's given out points quite convincingly that he has basically gone back to the drawing board and is starting over from scratch, or close enough to it to make no difference. Why this has happened, only Tom can say, but one can make a few educated guesses. There are two likely scenario's I can see here, and I'm just speculating... but either the "team" that Tom had assembled never delivered anything but empty promises and Tom finally got fed up and switched teams, putting him at square one. Another possibility is that he did in fact get some boards back and things just didn't work out like he was hoping, which means he had to go back to the drawing board. I give equal credence to either issue, but the fact that he has absolutely nothing to show for the efforts indicates that he is either starting from scratch or never got off the ground to begin with. In either case, a mid-January launch from Tom at this point is exceedingly unlikely, and if he does manage to get something out by the middle of January, I suspect it will underperform and the power consumption will be much more than he's indicated at this point. I think he was basing his power and hashrate estimates off what his previous team was telling him, and he's all but admitted that previous team was useless... so any estimates coming from them are going to be suspect. Right now, I would say out of all the ASIC vendors, Tom is the most likely to fold up shop if anyone is going to fold up.
Avalon
Avalon is like the turtle... slow and steady and they will eventually get there. What you end up with is going to be large, loud and hot while it tears through kilowatts like a Silverback through a banana plantation. Will it perform at the hashrate advertised? Absolutely, I think they will nail that, but the cost to reach that performance at 110nm is going to be crippling to anyone but those with free power. The fact that the Avalon team has publicly stated that anyone not using free power should not be mining should be a major red flag when it comes to people who have to pay for power and what Avalon is going to bring to the table. This is to say nothing of the environmental cost and how irresponsible it is to advocate mining inefficiently and not caring about the power usage. Having brought up the environmental issue, I do realize how potentially hypocritical it is to be a bitcoin miner and talk about the environmental impact of mining, but that doesn't it isn't and shouldn't be a concern, especially when alternates are available. Even the bASIC as a worst case will be superior to the Avalon in terms of power usage and should be used before using an Avalon unit to mine... but the environmental impact is another discussion.
I think Avalon is going to run into some integration issues with their all-in-one approach that they aren't expecting - how quickly they will overcome them is anyones guess, but it could potentially signal a delay, but it's not something I would bet for or against.
ASICMINER
What's going on here? Last I heard they might have chips before the end of the year. Their hashrate won't really affect the network as a whole very much, so it's not really an issue.

I think that about covers the leading ASIC scene apart from BFL. That said, with Tom looking like he's either down for the count or severely delayed, the real race now seems to be between Avalon and BFL. We are still on target to ship before Avalon, so that is not really an issue... but I was considering what would happen if Avalon pulled a slick one and was able to ship much earlier and something interesting occurred to me.
Avalon has 300 units they want to ship in the first batch - ok, at 66 GH/s, that increases the network hashrate about 20 TH... That is less than half the current network hashrate, which is comprised of a large portion of GPU miners. Adding 20 TH to the network would knock many of those GPU miners out of the profitability envelope, resulting in a net increase in network hashing power between 5 - 10 TH by my estimations. So even if Avalon shipped tomorrow, it would not throw difficulty out of whack too far and would not be catastrophic for any of the other ASIC companies. If Avalon sticks to their timeline and is truly able to ship all 300 units in a reasonable time frame, the network hashrate would be affected only in a minor way before Avalon runs into Chinese New Year and everything is on hold for a month... That means the total increased network hashrate between now and March (at the earliest) is 5 - 10 TH if no other ASICs ship. This does not necessarily include ASICMiner, but the future of ASICminer is kind of murky at this point, so it's hard to predict where they will end up and what effect it will have.
