Try searching for wii u titles on any of these stores:

e.g.
http://www.play.com/Search.html?searchstring=wii-u&search...

http://www.amazon.com/s/ref=nb_sb_ss_sc_0_4?url=search-alias%...

Tekken, Pikimin, NG3, Luigi's Mansion 2, Super Mario, AC 3, Ghost Recon, etcetc

except for the mention of Bros Brawl on play.com, the rest sounds reasonable.

All those games — with the exception of Luigi's Mansion — have been officially announced so will be coming to Wii U at some point. Play lists LEGO Batman 2 for Wii U which hasn't been announced, but the others are dead certs to release on Wii U. Not at launch necessarily, but at some point, sure.

Luigi's Mansion 2 is actually listed as a 3DS game, not a Wii U game.

@Wesker It was listed for Wii U a week or two ago iirc. Seems it's changed now

That's cool. Good to know.
