i don't really know. the only one i can think of that i think stands a reasonable chance is K. Rool. but as past has shown reason isn't really a factor in how Sakurai picks his slots.
i would think that 3rd party is done. going beyond the 3 of Sonic, Mega Man and Pac-Man would be too much imo. we're still lacking a new retro WTF character (along the lines of Ice Climbers, R.O.B., Game & Watch) although Wii Fit Trainer already fulfills the WTF role quite nicely.
i'm still pulling for Paper Mario.
