Today Capcom released details of the new content coming this month - amongst the bug fixes and balance changes, there will be the option of creating eight-player lobbies, the DLC shop will be open for business, challenges and combo trials will be available, and the first DLC character (Alex from SFIII) will be available to purchase.
So yeah, if this update goes without a hitch players should be receiving all of the content that really should have been in the game from day one. Sounds harsh, but after the generosity of Super Street Fighter IV this game felt a bit rushed in terms of missing features.
