Wii games on WiiU look like HD remakes.

Anyone seeing improvements with Wii games on the Wii U was either using an awful connection when playing on the Wii or are seeing slight benefits over HDMI than they were with older connections on the Wii. The WiiU does nothing to Wii games apart from play them. A Wii with a decent component cable at 480p looks identical to a Wii U outputting the same games.
