I'm definitely keeping my eye on this, and I have some hope. The 3v3 format almost definitely means the removal of assists, which were stupid in Duodecim. They basically made the game all about whiffing moves/air dash cancels to build meter so you could punish dodges with Kuja/Sephiroth/Jecht. Made EX a shadow of its former self, too (RIP Gabranth).
Overall, I'm looking forward to seeing what they do with this game.
