Well, the initial presentation was pretty important. The whole story with 'kinetct' and 'game discs that need a code activation, and another one if you want to lend your game to a friend' immediately turned most gamers(the variety that doesn't mind having a console) towards PS4(no code activation for games, no extra peripherals required to enjoy games).
MS did try to fix these issues but people don't forget that easily. Xone needs good exclusives and it needs them to be presentable at the next e3.
Speaking of exclusives and such, why the hell would they announce a PC release for Dead Rising 3 this early? That game might have helped the sales a little... There is also D4 which seemsed to be an interesting game at first glance, but guess what! KINECT ONLY BABE!!! ...immediately lost interest. And last but not least, the semi-favored game(by maybe a few die-hard loyal Xone fans...if one could imagine that!) Ryse - Son of Rome ...god lord, read the story for yourself, it's like puking on a pile of ****!
