When it comes to strictly first party support, I think it'll be fairly even.
When comparing each Nintendo franchise on both systems side by side, what I feel is:
(Wii vs. Wii U)
Super Mario Galaxy 1 & 2 >> Super Mario 3D World
New Super Mario Bros. Wii < New Super Mario Bros. U
Mario Kart Wii < Mario Kart 8
Super Smash Bros. Brawl < Super Smash Bros for Wii U
Donkey Kong Country Returns < Donkey Kong Country: Tropical Freeze
And that's for the ones that both systems have received.
As for the Wii 1st party lineup:
It had Metroid Prime 3: Corruption, Punch-Out!!, a console mainline Animal Crossing game (City Folk), a console Paper Mario, (Super Paper Mario), a console Fire Emblem game, (Radiant Dawn - and no SMTxFE doesn't count).
HOWEVER:
The Wii U has some games that the Wii didn't, like:
A new Star Fox game, Pikmin 3, Hyrule Warriors, Super Mario Maker, and the soon incoming SMTxFE. So it has some titles of there own in its favor. Oh, and of course, Splatoon!
As for games the Wii U will eventually get, that the Wii already has, we'll have to wait and see.
Zelda Wii U, I know will be amazing and one of my favorites on the system. However, it's going to take A LOT, for a Zelda game to top Twilight Princess and Skyward Sword for me (Especially, Skyward Sword.)
Xenoblade Chronicles X has a better chance, as I'm loving what I've been seeing from that game, and I absolutely loved Xenoblade Chronicles on the Wii. Based on my 1st impressions of never having played X, I'll say those 2 will be tied, for now. I'll get back to you on that comparision after I've beaten X... which may take quite a while.
So in conclusion, for now, the Wii still holds the edge (1st party of course), but it may change once it's all said and done.
