That would be 200m$ worth of BFL hardware... Not going to happen, leaving quite a margin for less efficient device to cover their investments ... at some point.
That would be 200M $ worth of BFL hardware
at current prices. There's a substantial financial incentive for them to drop their prices once business slows down - the marginal cost of ASICs is fairly low and the up-front cost fairly high, and they probably want to make as much money on that upfront investment as possible. Of course, that doesn't leave much room for purchasers of BFL's devices to cover their investments either.
