Do you really think that there will be 28nm FPGAs coming out in 7 - 8 months at an affordable price range? And if so, which companies are even doing R&D on a bitcoin mining solution?
-has all the FPGA competition been wiped out with this weapon ?
BFL's performance per watt is only about half of a 45nm FPGA, and 1/4 of a 28nm FPGA.
It looks fine today compared to 45nm GPUs and I'm sure their marketing talents
will generate some short-term sales, but 45nm and 28nm FPGAs can and will destroy this thing technically.
The payoff for a BFL unit today (832MH/s, $599, constant price/difficulty) is around 7 months.
28nm FPGAs will be mining in large numbers well before then.
