The biggest hurdle that the PS3 will have to overcome.

You want reasons why blu ray is nessicary for games i will give you some. First to add to my last post about stopts games. Blu Ray gives the ability to add hundreds even thousands of lines of new commentary, more sounds on the feild, more chants from fans, audio from coaches, and overall atmesfer of sound like birds, venders, trains and what not. Next you have space for many more animations, which EA has already stated both of these are reasons for needing blu ray for their future sports titles. Take a baseball game for example. On PS2Xbox a second basemen may have had 20 differant animations, now with blu ray that can be upped by 7 times so 140 animations making transitions look more fluid and putting more interest into every play. With more power also comes more responsibility and players can't look generic any longer which means each player should have a unique look which also takes a lot of space especially on a baseball or soccer game were you have so many players.
