We have our first official footage: http://www.youtube.c...5s236o#t=34m28s
I linked to the Direct feed because the standalone trailer I found doesn't show the second and far more exciting newcomer: Megaman!
That's right, Capcom decided to actually let Nintendo put Megaman in Smash Bros. 4. This is exciting news for us lovers of the Blue Bomber. Now let's hope they bring back Sonic; I'd love a three way duke-it-out between Mario, Sonic, and Megaman.
Anyways, the footage seems neat, the graphics are nice, and I like the cel-shading effect they have going for the 3DS version. Should be a good time; hopefully they took out the ridiculous tripping mechanic. I'm excited for this very much now, and hope they come out with more news soon. Maybe even a website that has a new update each week like they did for Brawl. Bring it on, Nintendo!
(And yes I didn't mention the Villager, he's about as interesting as Olimar. That is, not very.)
