I can picture Square bringing Final Fantasy III (japan version) to Wii U. That would be pretty cool if updated. It was a game that was in the miiverse "leak" a while back.

Also, I think Xenoblade 2 will be playable. I think it's a lot closer than some think, they've already shown it, it's had a long development time already, and the video they showed seemed pretty playable. Also, Monolith seems pretty capable of putting together a giant, well-polished game in a relatively short time frame.

I'm all for Goku in the next Smash Bros., course who isn't hehe.
I wonder though if Sonic n Snake will return, well more Snake then Sonic as the latter is pretty much a given, atleast it better be. :L

I would imagine that third party characters appearing in SSBU would be dependant on those characters appearing in games for the 3DS and Wii U. Which means Snake won't be there.

^That would make sense, but I don't remember if Snake was in any Wii or DS games.

They did remake the first Resident Evil for the GameCube, and then launched it for the Wii. Not even them can re-launch it so many times.

If they remasted one of them it will be 2, 3 or Code: Veronica. Or one of those Outbreak that were on-line. (Please not one of these!)
