Is Zelda U seriously the only next must have Wii U title?

Smash....then another year towards Zelda U? Xenoblade will be great, but is not a must have major seller.

Anything else?

You said it, basically Zelda U is the major seller on the radar.

Xenoblade Chronicles was like < 1 Million seller on Wii according to VGC so that's not a major seller.
Splatoon - unknown, but if it's not major known IP it's unlikely to move consoles even if great (see Bayonetta 2).
Mario Maker - Not a major Mario releae so I don't know.

Kirby & Yoshi should do decent.
