Why are they teasing the next big Super Mario with an artwork from Galaxy? Would you like a Galaxy 3 or maybe a HD remake?

That's his trademark jump, isn't it. I loved SMG, but I don't want the new 3D Mario to be Galaxy 3. Galaxy was great while it lasted, time to move on.

They won't do a pure Galaxy 3. Elements from Galaxy in the new entry are likely but a pure sequel would be a major dissapointment. Wii U needs something we didn't have before and they will deliver like they always do with the 3D games.

I think they just want a Mario outline. The people doing the promo work on the website probably haven't even seen the game.

I would be very sad if the Wii U's 3D Mario was a sequel to Mario Galaxy. I love both games to death but I don't want 3D Mario to get stuck in a rut like the New Super Mario series.

no! just no!....

This!

NO!!! I love galaxy 1 and 2 but it wouldn't be right for a third installment! At least give us a Sunshine 2 if you insist on a sequal but don't even consider galaxy 3 Nintendo!!!

You have been warned!!!

While I'd rather see them move away from the galaxy concept for the next 3d Mario game, if Nintendo did happen to make galaxy 3 I wouldn't exactly turn my nose up at it as I'm sure it'd be bigger and better...however, like many here, I'm sure it'll be a spiritual successor rather than an actual sequel...
Sunshine 2...hmm that could work. Sunshine wasn't my favourite 3d Mario but it'd be interesting to see em outdo it.
