Launching a new console a year or two earlier while the Wii was still hot (and not largely forgotten), before hype for Kinect had kicked in and while touch screens were still new and novel would have helped.
However, launching WiiU specifically a year or two earlier probably would have put Nintendo in a worse position. Nintendo took first place this gen by getting away from the complexity of the dual analog controller and making a system that anyone could enjoy. Following that up with a system that then reverts back to dual analog alienates the audience that Nintendo won over with Wii. Lacking graphics/power that significantly outclasses the other existing systems (and it would have been either less powerful/more expense 1-2 years ago), alienates it from core gamers. So all that's left is diehard Nintendo fans - regardless of when it launched.
Rol is right. Supporting Wii until they actually had a good idea for a console probably would have served them a lot better. Certainly NSMBU (or Wii2 in this case) would have sold millions on Wii already and Wii wouldn't be so devoid of games if Nintendo was still supporting it. Still Wii was getting old/stale and a new console was due.
