Actually, at this point the reasonable thing is to make a bet on the actual site where bitcoin bets happen:
BitBet.
Unlike the dubious venue the OP linked, the betting here is a little* richer. Also, you can use your own BTC addy as a refcode, just as I have.
So far the odds are something like 750 : 1 against BFL. Need more proof than that?
*For any value of a little that's much larger than a lot.
@Micon: go ahead.
I see there's a 10% error margin. That means that BFL could deliver a fully working ASIC unit doing 60GH/s but if it uses 67W instead of their claimed 60W (but still less than every competitor) then the answer still comes out as no. However, it doesn't actually say if "advertised spec" refers to the hashrate or to everything...
