Nintendo doesn't have anything bigger than Mario Kart and Smash for console, and the PS4 and Xbox One will finally be getting some games at that point, so I expect this to be the best year for the Wii U.

Its not unheard of for a platform to sell better in the years after its biggest hitters released, we saw this with DS, PS3 & 360 last gen so it is very poasible for Wii U to sell better next year than this year.
