Ive only played the Wii twice, but it was refreshing and different, Wii Sports definately offered next gen gameplay.
I mostly game on the HD consoles and this has been one of my biggest pet peeves. its like its the same game from last gen. just bigger with better graphics. I do have to give props to R&C Future Tools of Destruction, they implimented Sixaxis controls very well, Oblivion felt very next gen to me when i played it, though it was very repititive. The other game that I have to say is next gen, and i know probably a lot of you wont agree is MLB 08: The Show. The ambiance of the game feels very lifelike, this wouldn't have been achieved last gen.
