Pikmin 3, Wonderful 101, Wind Waker HD, and Donkey Kong Country are games I will most likely buy when I have a Wii U.

X(enogame), Smash Bros, and new Zelda are games I will buy a Wii U for, so I'll pick one up when the first of those is close to release. Probably around this time next year.

Pikmin 3, Windwaker, SuperMario3D, Smash Bros, Mario Kart 8, Wonderful 101, Bayonetta2, X, Donkey Kong, Sonic Lost World - Damn, better open a savings account

Definitely getting near launch:

Mario Kart 8
Mario 3D World
Zelda Wind Waker HD
Super Luigi U

and

Watch_Dogs

Maybe some impulse buy like Donkey Kong, X, or another 3rd party game like Batman. For some reason I actually want to get Injustice but it's released already. I'll likely won't get these few games in the near future though.

X
Smash Bros
Mario Kart8
X
Bayonetta2
Pikmin3
X
Wind Waker HD
Watch Dogs
Wonderfull 101 (may wait on the reviews fo this one)
Oh, and X.

Despite being extremely disapointed with what the showed for SM3DW, I will probably end up buying it. I also have Darksiders2 on my list that I will probably buy soon.

And while I'm at it, if you are doing some ''marketing research'' like you say, I think I might aswell tell you about the games I already have:
Nintendo Land
Zombi U
Arkham City: Armored Edition
Scribblenauts Unlimited
NSMBU
Lego City Undercover

Quite a healthy list for my quite honestly.

X
Mario Kart
Smash Bros.
Wind Waker
Mario 3D World

And likely also

Pikmin 3
Bayonetta 2
Wonderful 101

From 3rd parties

Watch Dogs
Assassin's Creed IV
Batman Arkham Origins
Scribblenauts Unlimited



So quite a good list.

Most of Nintendo games, ZombiU, Lego City Undercover and in future X, bayonetta 2 and the wonderful 101 maybe
