Link: My main in melee. I practiced every day with this guy, and kicked some major butt. With his upgrades in brawl, I look forward to playing as him again.
Pit: I've been keeping an eye on this guy ever since the original brawl trailer. He looks swift, fluid, and he has amazing recovery.
Sonic: This guy is all about speed, speed, speed, and his b-moves are extremely cool. Coupled with the fact that I love the Sonic series, this blue hedgehog looks like he'll get some hefty playtime.
Wolf: This guy looks awesome, and from what I've seen, he has a different enough moveset to set himself apart from fox and falco.
Lucario: With his unique ability of powering up his attacks as he takes more damage and his wicked final smash (say it with me now: KAMEHAMEHA!!!) Lucario looks like what everyone wanted mewtwo to be.
