1. Rosalina & Luma (puppet character in Smash is gonna be rad and I wanna try that)
2. Little Mac (that speed! that super armor! those dodges! need that)
3. Mega Man (don't feel the need to explain this one :P)
4. Villager/Wii Fit Trainer (coold newcomers but I'm not too excited to play as them)
Not a newcomer but I reeeaaally can't wait to get my hands on Dedede. I hope his mechanics have been touched up a bit from Brawl.
