They'll probably just get their ass kicked by Sony and there will be more PC focus. That's all. Right now, barely any new games have ANYTHING interesting to offer. In the last half a year, I enjoyed:
1) Witcher 2. Made for PC, great unique gameplay, great graphics, good story.
2) Battlefield 3 - great graphics.
3) Space Marine and Dawn of War - Warhammer 40K and entertaining gameplay.
4) Mass Effect 1/2 - great story, great gameplay, a unique interactive storytelling game
5) Skyrim - enough said
6) Just Cause 2 - Just Great.
Right now, the only thing I'm looking forward to playing is Mass Effect 3 (and moar Skyrim). I don't even want to buy a second 560 Ti despite having the money for it - why would I? 90% of the games that are coming out nowadays are complete junk, not worthy of even being mentioned. They'll have to come up with something worth buying either because of amazing graphics or amazing gameplay with okay (console-level) graphics. In the first case, they'll have to shift to PC and in the second, it doesn't matter if the graphics hang on the console level for a bit more... they can always follow BF3 way and develop for PC then port to console so that everyone is happy.
I'm REALLY wondering why the hell isn't anyone trying to resurrect old franchises like Redline, Populous or Dungeon Keeper. Made with modern graphics, those would sell SO well!
