What's the point of no return for WiiU?

[Declan]

With hindsight, you could say the point of no return was E3 2011 . This was the show that highlighted Nintendo's abandonment of Wii support (meaning no home console momentum going into the new home console's launch) and the introduction of an expensive but uninspiring controller that would make the console prohibitively expensive for many potential consumers.

I expect a modest boost for the WiiU on MK8's release, which should signal to Nintendo that there is no hope of salvaging the wreck they've created with this misguided attempt to innovate.
