The Wii U will not be discontinued until ATLEAST 2017. The Wii U has so many games this year that will boost sales incredibly. Wii Fit U, DKC:TF, Mario Kart 8, SSBU, Hyrule Warriors, X, Bayonetta 2, Hyrule Warriors, Watch Dogs, Project Cars, and other unannounced games.

how will watch dogs improve wiiu sales when it's also out on every other console? COD Ghosts and ACIV didn't boost WiiU numbers.

and guess which version of watchdogs, ISNT on the preorder list?
