I have played a beta version of Super Smash Bros. 4 and have worked on the promotional trailers, posters, and upcoming advertisements. I have a little bit of info, the most on the newcomers (promotional posters and trailers). It appears that there are only five newcomers left to reveal. Isaac, the hero of the first two Golden Sun games, has been upgraded from Assist Trophy to a playable character. He looks great in HD, I have to say. There are two Kid Icarus characters: Hades and Palutena. Hades is a blast to play, I must say. He looks a little strange at a smaller scale, though. Ghirahim is also a newcomer, and he is fabulous! The final newcomer is Takamaru. I think he looks ugly. As for veterans, I only know that Yoshi and C. Falcon are back for sure. The "new" veterans are Roy and Mewtwo. They get promotional posters like they are newcomers even though they appeared in Melee. In my short time playing, I found Kamek, Duck Hunter, Prince Sable, Eggplant Wizard, and King Hippo to be new assist trophies. The only new stage that I can remember well is a Donkey Kong Country stage. I think there was an Underworld stage too.
