Zoroark:
Chance: 13%
Mainly 'cos of the number, but honestly it is low. Illusion would be bull in smash, or not work at all, and his move set doesn't set him up that well for a fighter either. Ultimately he'd be a replacement for Lucario who I believe does even need to be replaced. I give him a slight chance because Pokémon company gives a lot of advice to sakurai for their franchise, so if they're caught up on him there's a chance, but they appear to have more love for Keldeo and Genesect than anything else at the moment.
On a side note Keldeo'd make an interesting smash fighter, though I do love me my quadrupeds...
Want: 0%
Illusion would be horrible in smash, and without it he'd not be Zoroark, so no thank you.
Simon Belmont: 22%
Third parties are difficult, and Konami already had Snake.. Now, if Konami decide to exchange snake for someone more fitting Mr Belmont is probably the lead position, but with the rather poor reception snake received in brawl, and the likely reluctance to cut their first choice character, I don't see it happening. The question however is how everyone else is going to feel, but I suspect people will be fairly similarly minded, so I'll just put my chance score for tomorrow as my prediction today.

(Gah! Goo many 10 nominations! I'll never get my slime to be voted on at this rate!)
