Sounds a bit too low for me on all systems exept maybe the Vita. Sales will go down a lot for sure since practically no game comes out besides MKX, but that just seems a bit too much. On Nintendos side, the Direct and Etrian Mystery Dungeon should push the 3DS a bit, but not too much; and Wii U seems to be at it's baseline anyway, so I don't expect that one to drop by too much, either.
So my prediction:
Wii U: 68,000
