News: More details on Square Enix's 'next-gen' RPG - ComputerAndVideoGames.com

I have to say, with Kitase talking about how popular action RPGs are and Squenix's announcement they are going to release an FF title every one to two years, I wonder if there is a possibility this may be FFXV. Its most likely an original IP but it is weird with all the other info SE has been announcing lately.
