Big nothingburger, since there is nothing he mentioned that really reinforces it being Dragon's Dogma 2. Still just one big assumption. Could be anything. People are grasping at straws here and are going to be let down if DD2 isn't shown.
Also if you reread that particular sentence, it's in reference to "Arisen". I assume they're referring to "Dark Arisen" (i.e. the remaster for PS4/X1) since there is no "Arisen"... unless of course they're stupid enough to name the sequel that (which would cause a lot of confusion I'd imagine).
