Seeing as how the old Super Mario Bros. film bombed, I don't think so.
Nintendo has not announced a super Mario galaxy 3. but it's possible
There is only a Super Mario Galaxy, but there wont be a Super Sonic Galaxy.
yes
probably not now that the 3ds is out, but im almost sure that super mario galaxy 3 will be on the 3ds: super mario galaxy 3ds. it has a nice ring to it
Not that I know. Nintendo did not announce anything like that. There is going to be a "Super Mario Galaxy 2" tough.
So far, there have been no announced plans for a third Super Mario Galaxy game.
Yes.
No. There won't even be a '3.
The Characters starred in Super Mario Galaxy 2, are the same in Super Mario: Mario Luigi, Peach, Toad, and the other character that will star in the game, Yoshi.
Most likley no, it is probally going to be on WiiU
i doubt it, of they do make a new Super Mario series (Super Mario 64, Sunshine, Galaxy, and Galaxy 2), i think that it should be a different theme.
I don't know but I there is one coming next year or a Super Mario Galaxy 3 for the Wii U.
