When will Wii U owners be satisfied enough to accept a new console?

[MDX]

WiiU's potential is yet to be fully tapped.  

I hope it stays on the market for at least 7 years before the next console gets announced.

I wouldnt want Nintendo to launch a console too early.

Let the indie developers grow on this console to become major players on the next console, and 

Nintendo will solve its 3rd party issues.
