If Wii U had been a smash success, like wii, sony and ms would obviously have put more focus and development into their own tablet controller, right? Lets face it, vita remote is no where near the same as gamepad. Vita remote can't act as a second screen, it only mimicks the offscreen feature. And smart glass is not an xbox controller.
So if Nintendo turns the Wii U around, they will be the only ones with a true tablet controller with 100% attach rate. So if and when the competition tries to copy like they did the wii remote with move and kinect, they will still be behind.
What are your thoughts? Btw im not suggesting this was the plan all along. Do you think the fact that sony and ms didn't copy Nintendo's tablet strategy could help the house that Mario built?
