I'm guessing there are going to be a few more veteran fighters before a newcomer is revealed.
My guess is that veterans will be released in clumps before a newcomer.
Yoshi, Peach, Meta Knight, Zelda and Ice Climbers.
Then perhaps a new version of Pikmin and Olimar. Maybe not even having Olimar, but one of the new characters from Pikmin 3. Also incorporating the flying and rock Pikmin into the Pikmin chain.
And then Little Mac.
Luigi, Marth, Ness, Captain Falcon, Jigglypuff, Wario, King Dedede, Diddy Kong, Lucas and Pokemon Trainer the next clump
