Voted for Mario since that would be the best option for a system seller and a kick ass game.

i feel like they need a mario game for launch, because the 3ds didn't sell very well until mario land and mk7 came out

Rather have a 2D Mario but I wouldn't mind a 3D either.  I believe they should probably put the 2D version out first to get sales to explode like they did on the Wii. 

Now that is a pretty hard last question.  The usual Mario lineup would trumph Wii Sports overall but if you were to just compare one 2D Mario game with Wii Sports then I'd probably pick Wii Sports.  It would be a tough call though....

Now for the perfect launch...  Have a Wii Sports pack in and have 2D Mario for sale.  Might as well throw in Mario Kart for a hat trick.

I'd imagine it'll launch with a Wii_____ title, similar to the Wii and then follow up with a new Mario, some secondary series (Starfox, FZero, Metroid) and others within a year.

Where's Zelda on your list? A HD, WM+ Twilight Princess would be a great library booster in the first year too if not an all-new Zelda.

Personally though, no new Mario, Kart, Zelda, etc. game would get me to even look at Wii U. An HD and highly enhanced Endless Ocean might entice me though.

I want F-Zero/Pikmin 3.

They need Mario.

assuming they launch 3 titles

i want the following
a zelda game
2-mario party 10
3 fzero

I want Smash Bros damn it!

..I know it won't happen at launch.

Suspicious quotation marks.

A Super Mario game would definitely be the best system seller. Doesn't matter to me if it's 2D or 3D, as long as it's good.

Personally, I'd root for Zelda, but that's pretty unrealistic for Wii U's launch.

Baten Kaitos.
