Obviously we can see Warrior Of Light, Onion Knight, Y'shtola (FFXIV) and Terra, Cloud, Lightning in teams of three.
Gameplay seems as hectic although it's still a mystery is the Assist system from 012 is used. But biggest news is a representative of FFXIV is in, bringing speculation that new Final Fantasy characters may be announced.
That said, the other news is that it's only in Japan. Japanese fighters tend to be release in arcades there before getting news if any, about a console port. Take for example Pokken...
So for those hoping this comes out on PC or consoles, cross your fingers.
p.s Hoping for Auron.
