Asicminer has fallen behind, as there is a great deal of competition now. When they were dominate, there was not nearly as many ASIC designs out there.
However it's not 'over' by a long-shot. The company is still in a great position to maintain a sizable chunk of the mining network. Even today they are a fantastic deal for their dividends, paying over a 40% yearly annual return, making buying Asicminer shares a good alternative to mining in this super-chaotic period of change over to all-ASICs.
For Asicminer's future, a lot depends on the next month when new mining gear comes online, and hopefully around the end of the October, when the gen 2 design is revealed. Asicminer does have the knowledge and resources to pull off something impressive.
Friedcat recently purchased some forum advertising spots so there's a lot of anxious people waiting to see what that will be about, including myself...
Bitcoin ASIC manufacturers competitions can be likened to:
A single swimming pool of water where each manufacturer is trying to suck liquid from the pool with an ever bigger motor.
ASICMiners pump is sucking at 20 gallons a minute while BitFury pump is doing 160 per minute.
Which means that most of the wealth of BTC is being sucked towards BitFury.
BFL's pump is just broken and they hired a moron to put in the pump. The moron filled the pool with liquid nitrogen and people are passing out in and around the pool with some falling into an abyss of poverty. Don't run that pump of poverty!
