Final Fantasy XV An Action RPG?

Over at Edge, Yoshinori Kitase, the producer for Final Fantasy XIII-2, is saying the next numbered Final Fantasy game could be an action RPG.

"I think the nature of the franchise is to present something new each time. In the global market we see many players moving away from games that used turn-based systems toward what you might term an action-RPG."

Personally, why make this a numbered game? Final Fantasy has, traditionally, been a menu based RPG. When they have decided to really do something different, Square Enix has not numbered the game. This has spawned a series of games doing this! Look at Tactics or Dissidia. While I'm sure the vast majority of Final Fantasy gamers would still buy this, it makes me wonder, is the Square that made the classic Final Fantasy games dead?
