IF the Wii U is killed off, should I.... ?

It won't be discontinued at least two more whole years. But you definitely don't expect some more new unannounced games, saying that Wii U already have great 10-15 exclusive games.

Also my 5 years old loves games like NSMBU, Mario 3D World, Mario Kart and Splatoon. :)
