According to
eventhubs, the following features will be available in the upcoming SSF4:
• A team battle mode that is a 2 vs 2 set, but it can scale up to 4 vs 4.
• A Replay Channel where you can play replays of matches while voice chatting with other players.
• An Endless Battle mode with up to 8 players and voice chat, which sounds a lot like the quarter matches in SSF2T HD Remix.
• Apparently a 'tournament mode' will be delivered as DLC (downloadable content).
What's more, check out the scanned image from the Famitsu Japanese game mag showing the bonus stages as well the online menu for SSF4:
Street Fighter 4's online modes were pretty lackluster if you ask me, so team battle and tournament modes should be welcomed additions to online play. Not to mention 8 news characters, new stages and background music, bonus stages as well as
tweaked gameplay is making this title a worthy sequel to SF4.
