While it's already been stated that the four new characters for Tatsunoko vs. Capcom will be announced at this year's Tokyo Game Show (TGS) which is scheduled to run from September 24-27, Capcom also revealed today through their Twitter feed that several new games will be announced there as well.

Now, Capcom obviously has a lot of franchises, and it's possible this won't mean any new Street Fighter (or other fighting games) will be announced there.

They originally announced Street Fighter 4 at a Gamers Day event in London in 2007, this event was later killed in favor of the new 'Captivate' shows, with this year's gathering happening back in late April.

While Capcom certainly doesn't have to wait for a major event to make an announcement for the upgrade to Street Fighter 4, the Tokyo Game Show is on par with E3 for size and attendance, so IF they were going to make an announcement at a major show this year — this would likely be it.
