Yoshi-P said to eurogamer there is the possibility of a PS4 version of FFXIV but first they must deliver the promise of a PS3 version.

Also the beta will be towards the end of Sept, PC beta will start before PS3 beta and when PS3 beta is out we will be playing with PS3 players.

Seems like Yoshi-P really wants to get as many customers on board as possible.
