Super Street Fighter 4 3D Edition will have online multiplayer support. Word comes via G4, which spoke with Capcom's Yoshinori Ono at last week's Nintendo World event.
There will be two different types of online multiplayer in the game: worldwide online play and Channel Live. The former is pretty self-explanatory (this is the place you go to fight people from all over the world), while the latter is a place to go to watch live matches. Of course, there are also the figurine-collecting and random street fighting modes, which were previously announced.
