By the way, since we were talking Veterans earlier...
My ranking of vets as far as personal desire and play time I would put into them:
Lucas > Squirtle > Wolf > Roy > Snake > Ivysaur > Ice Climbers > Pichu > Young Link
Remember that this is what I want, not what I think is likely. It is difficult to give chances to DLC as we still don't know what "the rules" of DLC are as we have no idea what (if anything) is planned beyond Mewtwo. The chances of the Ice Climber in particular are hard to gauge since I feel that their DLC chances are linked solely to a New 3DS version of the game.
Wolf is the only veteran character that seems truly likely to me due to several facts. He is mostly unique, he is featured in a marquee game (developed by Miyamoto no less) that is scheduled for release later this year, he is popular both within the Smash community and with out, and most importantly, Sakurai likes the character.
I am hoping for Lucas and would love to see the Pokemon cuts come back. The issues with Squirtle and Ivysaur is that seeing one come back without the other would be strange. A stand alone Charizard does not seem strange, but seeing two out of three of trainer's Pokemon come back would make the third stand out due to it's absence. They would therefore take up two slots, which would give Pokemon 3 out of a limited number of DLC slots. There is also the issue of Pokemon (and gen 1 Pokemon in particular) over saturation. Pokemon is a huge franchise, but it seems to me that Sakurai realizes that he needs to somewhat balance the number of Pokemon compared to other series representatives. Pokemon is the only series that received cuts in both Brawl and Melee, and is the only series to receive multiple cuts both times. That says something to me.
