It'd be cool if we could get more Fables for the PC, but Peter made it clear that Fable 2 and 3 are gonna be X360/PS3 exclusive.
PC gaming's huge hurdle is piracy, but groups like Steam help buoy that. I love steam's anti-piracy function, it works wonders. A bit annoying for those with slower internet conections, but it keeps smaller game developers afloat, because their product isn't pirated to pieces.
