EA Sports still refuses to make a statement on SSX's rumoured head-to-head multiplayer update, but it's confirmed it anyway, via the medium of teaser video.
Unfortunately, the video only shows online head-to-head multiplayer; there's still no indication of couch versus mode. It's also not yet clear whether the new mode will be added via paid DLC or a free title update; the game's Twitter describes it as "content", which could go either way.
The video is in addendum to a couple of screenshots and an earlier teaser video which were slightly more vague.
SSX launched for PlayStation 3 and Xbox 360 in March this year and was well-received by critics; it didn't make a major splash on sales charts but continued support suggests EA is happy with its performance.
