I don't think stages outside of the character's ones will have a high chance of getting in. In fact, I think it's pretty low.
You must've been thinking about one particular stage you want, or else you wouldn't bring it up. What is it that you want to see in Brawl?
All I'm saying is that (non-super-popular) series with no fighting characters aren't likely to even have a say in Smash Bros.
I would like to see more specific Pokemon stages, something like Giant Chasm.......instead of the stupid stadiums.
I'd rather have N's Castle, but Giant Chasm would be nice too.
