Once Zelda U is finished, I think Nintendo is pretty much finished with the platform.
I think maaaaaybe Retro Studios might be doing something like Diddy Kong Racing U as the swan song in 2016.
By that time though Nintendo will have given the Wii U all the major Nintendo IP. There's no point in dragging out an unsuccessful console. It just hurts the company by devoting resources into a dead end.
The GameCube really didn't get 5 years either, Nintendo pretty much stopped supporting it after March 2005 with DK: Jungle Beat's release. The rest of the major games were basically outsourced projects and Zelda: TP was moved to be a Wii launch title with the GCN only getting a limited, late release of the game.
