Nothing has been confirmed yet. Given its a working title it could very well change before release. Also it seems to be a PS4 exclusive and Dragons Dogma was released on 360 and PS3 so it would be strange for them not to get the sequel.
I played Dragons Dogma on te 360 and there were lot's of complaints from that community about far fewer interest by gamers and support by capcom for the 360 version. Wouldn't be surprising if the sequel would be PS4 only.
Won't mind myself, because I'm probably switching systems anyway.
