That would be a very big list... some sequals, some HD ports and some 3rd party games would be awesome, but here is my dream list:
1080 Wii U
Wave Race Wii U
F-Zero
Eternal Darkness 2
Super Smash bros. Wii U
No More Heroes 3
New Super Mario Bros. Mii
Pikmin 3
Resident Evil 5: Gold Edition
Grand Theft Auto IV: The Complete Edition
L.A. Noire: The Complete Edition
super mario galaxy 1,2 HD collection
The Legend of Zelda: Skyward Sword & The Legend of Zelda: Twilight Princess HD collection
Star fox Adventures & Srar Fox Assault HD collection
Metroid Prime trilogy HD collection
Metal gear solid HD collection

What it needs is two or three well-established franchise entries such as Assassin's Creed, GTA or ideally Call of Duty, along with some of the more universally-liked first party series. Zelda would be perfect, most Xbox/PS gamers I know still admire Zelda, and F-Zero would also be quite appealing to non-Nintendo players. Mario, Kirby and DK don't seem to garner a lot of respect outside of the Nintendo playerbase, although a Mario game is generally a given at launch.

Personally I'd buy the console for £300 if the only games ever released were Mario Kart and Smash Bros :]

All these lists are great, I really hope they nail the launch with some exciting software.

My list:
The Legend of Zelda wii U
Super Mario galaxy U
mario kart (with more than 32 courses)
Pikmin 3
Animal Crossing U
New golden sun (like the 1st 2 not dark dawn).
And maybe a sequel to Rayman Origins.

I got this feeling there won't be a new Super Smash Bos any time soon and that would stink since I want to play that game the entire lifespan of the console....

Same goes for Mariokart, though I got more hopes for that one.

MH HD
XENOBLADE HD!

as well as the games i chose, it would be also great to see sequels to xenoblade chronicles, pandora's tower and the last story on the wii U

um i want a new castlevania and ssb and mk i be fine

That's all I need.

it doesn't, but with this thread, you can list whatever games you want, which includes your favourites or games that are about to come out soon on other consoles.

• Metroid Fission (after Fusion in the storyline but reminiscent of Super Metroid style)
• StarTropics 3: Insurrection (Zoda has control over the Earth; Mike to save the day again with his Yo-Yo)
• F-Zero Extreme (To fast, to wild, to extreme that it will rip your face off like in Total Recall)
• The Adventures of Bayou Billy 2: Back to the Swamp! (2 player co-op with Crocodile Dundee battling gators, voodoo priests, and the Swamp Thing virus)
• Castlevania: Cataclysm (2D Belmont bashing beasties is back in the classic style Castlevania!)

I know this is a "Dream" launch lineup, but realistically, this is what I hope to see.

-MARIO (I don't care what it is, Mario needs to be a launch game, like it used to be. Nintendo surely should have learned that lesson by now)
-Pikmin 3 (Most likely will happen)
-New F-Zero game
-New Metroid game
-New Star Fox game
-At least one HD remake, Wind Waker?

Some extra thoughts, I highly doubt we will see any form of Zelda, besides what I said above. The Legend of Zelda is almost always a no-show for launches. They usually come later, so I'm fine waiting for the Zelda HD we all want. Besides those first party Nintendo games, I want to see all that 3rd party support the Wii U seems to be promising. Nintendo shouldn't rely on it like they did with the 3DS launch (and we all know how that went) but they should have a good mix of both 3rd party and some strong titles with Nintendo characters we want to see in HD.

just wanna say, if there is any more than 32 mariokart courses the game will get reallllllllllllllllllllllllllllly long. In development and playtime.

New Mario and Zelda game at launch and that would be a great start.

Super Mario 64 2/Universe (jumping into paintings, punching/kicking mechanics needs to be back and secret bosses hidden in dungeons like Zelda style)
No More Heroes 3
GTA (Nintendo needs an other good sandbox title that doesn't involve with drugs)
F-Zero (Needs good online play)
Sonic 2d/3d title (Same gameplay like generations and colors)
Pokemon Adventure (Needs to be ether mature or target to neutral audience to all ages, still a good concept but it had two obsolete titles)
Sonic 4 Episode 2 (Meh why bother looks better then the first)
Digimon (Hack and slash with RPG elements thrown in)
Cave Story 2
Wario 3D Title (Loved the gamecube title)
Black Rock Shooter (a heroine title on psp that never got lunched outside of Japan)
Dynasty Warriors Transformers (Needs to be a better adaptation unlike the movie games and war cybertron which I'm not satisfy with)
Dynasty Warriors Gundam collection
Mother 1 and 2 remake
Mech Fighting Crossovers
Arcade shoot em ups (Nintendo is some what lacking recently)
