no you can't because the games being made for the PC right now are just PS3\Xbox 360 games with higher settings.
Yes, every game in the world is being built with PS360 in mind. Some of them aren't even made on/for PC and then downported. There are no games on PC, either (is this the modern day version of "PS3 haz no gamez"?). They're all console games.
C'mon man. That's a very macroscopic way of looking at the market. It is true that raising the console hardware baseline will raise many multiplatform games' baselines, but it's not a drastic shift from what we already have. Just more of it and better quality.
