@Kowenicki -> X360 was out a year before the PS3, at a cheaper price (and is still cheaper) and had a lot of games that were PS exclusives last gen (so people didn't see why they should wait for/buy the PS3) and yet the PS3 is catching up. For you this is not impressive right? You might have a problem.
And why do you talk about the Wii... he was talking about the PS3 and the X360. (because only those two should be compared, Wii is on another level on several things, the graphics, the gameplay (I mean core gameplay, not add-ons such as Move and Kinect), the install base and gamers aimed by the company etc.
