There are other startups hashing themselves and producing (and selling) ASIC hashing hardware, not to mention that GPU hashing is still going on and people are still joining just for fun, even if they won't care about profit.
Asicminer is hashing themselves and selling devices to people. Chips are now being sold as well, presumably all those chips will be hashing soon .. we're going to get flooded with hashes at an even faster pace now once Avalon and BFL buyers become the minority in the ASIC market.
