Now this is starting to look interesting.
The previous news we had only mentioned new V-Triggers. But according to X-Kira who is a dataminer that has given us correct info about upcoming things before, he found files that suggest that there are new V-Skills, V-Reversals and new Critical Arts as well.
Which could explain what's going on in this image of Chun-Li doing Kikosho.
Hard to imagine that just being a V-Trigger.
But I'm not sure if these new abilities we see in this trailer are just from the V system, or if they're getting new Special attacks.
Either way, this looks like a good step towards addressing some of the complaints people have about the game being too simple/boring.
Again this is a free upgrade coming in January.
