It'd be cool to play a new Skate version and all, but I don't really see how they could evolve to the next step as a game. Besides having diff spots/pro-skaters, I'm thinking they reached a creative peak with the 3rd one. Kinda like every new THPS version: its more or less the same shit every time. Then again, this is coming from someone who doesn't play video games that much these days.
Maybe Berra just wants to get the Berrics into a closer partnership with EA or something (take Black box's former space), which is smart I guess.
