Nothing like what the 360 does when you pop in Halo 1 or 2, or what the PS3 60GB BC did with PS2 games, i.e. make them look considerably nicer on an HDTV. I do not know what those consoles did technically when upscaling games from the previous generation, but I would say they were clearly doing something more than what the Wii U does with old Wii games.
