The assist trophies sound great. Hopefully they go crazy and we get tons of them (and quite a few third party trophies).
It would be great if they could get Capcom to let them use Leon Kennedy as a playable character, and have various assist trophies be based on Resident Evil 4 characters. Since they usually a Pokemon that does nothing, like Goldeen, they could have a RE4 assist trophy be Ashley, who hides behind your character. The chainsaw guy would also be cool as a trophy, but maybe too violent for SSB.
"You’re probably thinking that a Nintendog is a pretty poor assistant, since it blocks your view, too. That’s fine. He’ll help calm your mental state."
Masahiro Sakurai is hillarious. I love the funny comments he makes about the pictures.
