I'd agree with you if it weren't that there are several people on this forums who reported mining with their FPGA Singles. So in order for it to be a scam they have to somehow be in on it.
That wouldn't be the strangest thing to happen, but still it gives them some credibility.
Do you think that these are genuine products or just empty boxes?
On the price: Almost certainly down, this would be a massive blow to the credibility of bitcoin businesses.
Lol, that'd be a LOT of people to be in on the scam, without a single person having reported not receiving their FPGA. The FPGAs are real. I bought 10 of them myself (which I have since resold mostly to yochdog, who has been happily mining with them since).
Also, if any of you scam-callers wants to put your money where your mouth is, I'd be happy to counter your bet on betsofbitco.in. BFL will deliver. The question (in my mind) is when.
FPGAs are a completely different category -- you basically sacrifice raw performance potential and use off the shelf programmable chip arrays in place of doing a custom ASIC. Note that while FPGAs are more efficient than GPUs, their performance and cost is such that it's not worlds better. 800 Mh/s at 40W compared to 650 Mh/s at 350W means they're about an order of magnitude faster. GPUs on the other hand are about 30X faster than CPUs for hashing, and ASICs have the potential to be 30-50X faster than GPUs (and possibly use less power at the same time). FPGAs are real and people are using them, but FPGA vs. ASIC is like comparing a Visual BASIC prototype (that's missing a bunch of features) to a final C++ program.
As far as pricing goes, if ASICs begin shipping, pricing will tank. People will want to recover the cost of their ASIC hardware, and while not all of them are going to be interested in selling every coin mined, plenty will. Difficulty will shoot up, and if you can actually get 60 Gh/s at 60W you would have a system capable of mining about .7% of all BTC ($300 USD/day at the current rates) while drawing only about $0.20 in power per day. You could sell BTC at $0.01 UDS each and break even, so anything above that is profit (after recovering the cost of the $1300 hardware, of course). Personally, the day people confirm they're running ASICs (and we see the associated spike in block generation with difficulty following), I sell all my coins and wait to buy back in until we stabilize -- probably in the low single digits.
