To be fair Madden isn't exactly the game that I'd say would win me over to next Gen graphics wise. It's a port, a port of a current gen game, the differences aren't going to be that great. It'll load faster, have better textures, play smoother, but all these things will be miniscule. Same with Assassin's Creed 4, COD, etc. That's pretty much the reason Watch Dogs go delayed, so they could polish it up for Next Gen, they've probably already got the game all done on PS3 Xbox and WiiU they just want to release it all at the same time so you'll really notice the next gen copy.
