Little Mac is pretty much a shoe-in with the revival of Punch-Out!!, I think.
Stages from new entries in franchises, like a Super Mario Galaxy-stage and such.
Saki is a possibility, since he managed to make AT last time and there is now a Sin & Punishment 2 coming.
I guess some new characters from franchises already in the game are possible, though I wouldn't expect any(or atleast not many) from Mario, Kirby or Zelda since they already pretty much have their quotas filled. Could be someone new from F-Zero, someone more from Fire Emblem, possibly Isaac from Golden Sun if they make a third one (possible even if they don't).
