New Street Fighter IV announcement teaser?

After having been teased for the longest time, and then not appearing at TGS (except at supposed secret showings), Capcom Japan has now released a teaser for an announcement that will occur tomorrow at 5PM Japan time.

Click on the image to see the teaser.

The URL itself also contains the words "new warrior" which is sure to fuel speculation until tomorrow. So does this mean that the supposed Super Street Fighter IV (as hinted at this photo that was supposedly taken behind closed doors) is real? I guess we'll find out tomorrow at 5.
