Obviously, we're all guessing, but I think the 360 version will be much better in all areas, but in the same vein as the current version.
Those of use hoping for a more realistic game may be disappointed because that's not what the series is about. But if you like what the title offers now, you'll probably get a much better brand of that.
My point is that I don't think Madden adds or excludes anything by accident. The game is the way it is because that's how they want it. And they want it like that because their customers want it like that.
So I guess I agree with you except that it won't be the same game. I do think they will rebuild the engine and improve everything. But those improvements won't make for a better simulation like some of us want.
