Well, there are a couple games that will be "better" on the ps2. E3 comes to mind. However, that's only levels, and gameplay. What about overall graphics?
Also, the biggest price point of the xbox is that they have bottomless pockets, whereas Sony doesn't. When has M$ ever backed down from a market? If the DOJ was closing them down, or splitting them up, you can bet your arse I wouldn't have bought one. But jeez, just look at it. They're SELLING THESE THINGS AT A LOSS! They're gonna eat up market share just like the Iexplore vs netsc@pe battles. While it's not free, it sure is alluring to buy a system from a company that will spend years before it gets any returns on games. (ie, Dreamcast)
