Nov. 16 2012 Update --
Full Patch notes -- Release date has been
confirmed as January 29th.
Will SFxT finally become the awesome thing that it should have been? It's looking like it will!
There's a supposedly HUGE list of changes, but they're literally still being introduced as I write this, live at Comic Con, so we probably won't see a full list for a few hours / days. It's being heralded as a major revamp, though, along the lines of the free SSF4AE v2012 update-- and of course, SFxT v2013 will be a free upgrade as well.
Man, I can't wait to see the full list of changes coming down the pipe. For now, you can check out a few teasers at
Shoryuken.com.
The teaser/announced list of changes so far has confirmed slower health recovery, faster throws, better anti-airs for Tekken characters, less screen-freeze during zoom-in animations, and more.

Street Fighter x Tekken v2013 update coming this December-- err, January!
