There's really not any character I'm not looking forward to playing, but these stand out to me as the ones I'll want to try straight out of the case.

I think its stupid to what character that you WILL play as, and i thik it would be boring to play primarily as the character that you were in Melee, im gonna try all the characters and from the looks Diddy looks like a lot of fun to play with so im probably gonna play as him first :)

well i wanna try out all the new characters and some old ones like samus ganon and link

Samus
Diddy
Ike
P.T.
Pit
and Robot

Just watched a gameplay video of Wolf. it's pretty interesting actually. His pistol fires a big slow green beam like a canon rather than Fox's and Falco's lasers. He's high damage, low speed, but has some good combo A moves. His version of Fire Fox is definitely very different. Can't tell exactly how it works though.

i like toon link the best

since when did they say wolf is a clone

Er... hours ago, when he was first unlocked, but there is a video on youtube now where you can watch for yourself.

Samus (and ZSS) (my main, Samus rocks...even if she's nerfed in Brawl, it just means I've got my own handicap to brag about)
Sonic (fast and fluid)
Metaknight (fast attacks, flying, gliding, kickass!)
Snake (duh, it's Snake)

Link, my main man
DK, my 2nd main
Sonic, got to try him out

My brother will always play as Fox btw.
