Three unlockable characters have been revealed for Super Smash Bros. on 3DS and Wii U by Nintendo. Don’t worry. No spoilers are posted below.
I don’t want to post them here, because even Nintendo admits the reveals are a bit spolierliffic, so I’ll just link to them instead.
A couple you may already know about anyway.
Super Smash Bros. 3DS is out not and the Wii U version is out this fall.
