The problem is HW sales aren't going to continue unless they come up with a 28nm chip or something.
I'd have to disagree there... If they could produce a 2GH USB miner at an appropriate price point they could make a lot off of hardware sales.
They just need to focus on the markets where the other guys can't play.
They wouldn't be able to power a 2Gh/s mining stick without some new chip, since their old ones would draw too much power, I believe.
