What the... that would be downright AMAZING. And that's why I seriously doubt this is true. =\

I highly doubt that this is true.

That would be something really spicey to see.
I hope it's true. Would love to see that.

Only if he's an unlockable like Luigi was.

I would personally not like that to happen.

Maybe they said that Sonic would be playable in Brawl 2 with a Mario Galaxy themed stage in the game?

That would actually be awesome if they did it, despite the recent shitty Sonic games in general, I do still love Sonic the Hedgehog character.

Nooooooo this is just so wrong, sega gained a lot by having mario feature in there games, and i loved sonic appearing in ssbb
But what the hell will nintendo gain from putting a mascot whos career peaked in the early 90's and has declined with every 3d game since ?

WHY?

this would be so cool

it would bring all sonic fans to mario galaxy & possibly increase its sales too.

Playing with sonic on a second play-through could be cool.
