I can't wait to see what Nintendo has to offer especially with their 1st party games. So glad to see them make the jump to full HD resolution.
I can't wait for the inevitable announcements of:
-Mario Kart Wii U (I remember when i played Mario Kart in the arcades, the graphics were AMAZING! I thought MK Wii's graphics were just as good, can't wait to drop my jaw for Mario Kart Wii U.
-Super Mario 3D platfomer Wii U, Really hopes it will be like all the other 3D Mario console platformers where u enter a world and have to search for 1 of X number of stars at a time, i did enjoy Super Mario 3D Land but I prefer the console versions, I hope it to be a new location and kind of not a 3rd Mario Galaxy although I would still be hyped up for it anyway.
-Metroid
-Zelda (the tech demo was amazing)
-Bayonetta 2 (I have a feeling it will incorporate references to Nintendo franchises much like the 1st did with Capcom and Sega games) Also I have heard the 1st one MIGHT come to Wii U via eShop.

I have recently heard that Resident Evil: Revelations MIGHT come to Wii U, an achievement list had been leaked for the 360 version. So I'll probably pick this console version, the 3DS version is great.

Definitely has to be Injustice: Gods Among Us. Just the idea of having my favorite DC Comics characters duking it out is reason enough, but it's also coming to the Wii U!

Out of games that we know are coming, my top three have to be:
1.) Monster Hunter Tri Ultimate
2.) Zelda U
3.) Mario Kart U

Bravely Default
Etrian Odyssey 4
Fantasy Life
Unchained Blades
Devil Survivor Overclocked
Dragon Quest 7

Pokemon X and Y
Monster Hunter 3 G for 3DS
Denpa Men 2
Harmo Knight
Bayonetta 2
Pikmin 3
Lego City Undercover
Wonderful 101
Game and Wario
Bravley Defult
Fire Emblem Awakening
Prof Layton Civilization A
Dragon Quest VII
Ikachan
1001 Spikes
Fire Emblem Shadow Dragon (for 3DS VC hope)
Kirby Dream Land 2
Wario Land III

Nothing. I guess I'm just patient. With the exception of unannounced Retro Studios title/s.

Aliens and Monster Hunter.

I can wait for any game. Well, except maybe for Brawl when they were updating Smash Bros. Dojo

Fire Emblem Awakening and Pokemon X/Y

Animal Crossing New Leaf and Luigi's Mansion Dark Moon.

Lego City Undercover
Project Cars

Pikmin 3.

Animal Crossing: New Leaf
Pikmin 3
Pokemon X & Y

The only game I cannot wait for is New Leaf. Considering it should've been released four months ago.

The unlikely sequel to Code of Princess.

For Wii U? Pikmin 3 and Smash Bros. I generally am not impatient for games that haven't had any info released yet (with the exception of Smash Bros), and there aren't a lot of titles yet that I'm excited for barring Pikmin, I've been waiting for so long for this sequel!

Star Wars: Battlefront 3.

Zelda Wii U, Metroid Wii U, Super Mario Wii U, Mario Kart Wii U, Smash Bros. Wii U, Resident Evil Wii U and Metal Gear Wii U.

Pikmin 3, The wonderful 101, The new smash bros, aliens colonial marines

Super Smash Bros 4. That's probably going to be one of the best games ever made when it's finally released.
