If the xbox doesn't go blu ray then we may start seeing exclusive content for the PS3 over the 360. While you will get more levels and extras on the PS3 for $60 you will have to pay $60 for the basic game and then download the extras through xbox live most likely for a price. Take oblivion for instance. All that downloadable content at an added charge brought that game to about over 120 bucks where the PS3 version bundled it all together for $60. This is why they need to go blu ray, I know I would rather buy a game packed full of stuff then have to download it later and eat up precious HD space. this could turn the tide in Sony's favor if MS isn't careful.
