If it was that easy to penetrate the gaming market, then someone would have done so before MS. Do you remember Apple's attempt at a gaming console?
If MS tried to buy exclusivity, then Sony should have offered more for the developers not to leave. It's all part of the competition. That's what capitalism is all about.
Sony is all about making games better. If they just buy up all the games then where is the motivation to make them better? We all know MS doesnt care about making the industry better, you can look at their hardware and tell that they want to give the consumers the very least possible and get away with it. Dvd drive, relatively slow cpu, slower ram... Some of the eariler models didnt even have hdmi. Not to mention that none of them have any heatsink to speak of.
MS just wants to throw money at their problems instead of actually making a decent console.
If someone has 15 games they have spent $900 in games (at $60 each) so they are going ot go back to their rrodbox even if they hate it just so they dont have to buy all their games again. I know plenty of 360 owners that are tired of MS's ******** but dont want to lose or rebuy their catalog of games.I think it says something about the user experience and gameplay, when even after multiple hardware failures, people still go back to the Xbox and not PS3.
