I'd say it was pretty obvious that PS3 support wasn't going to last forever, and I say this as a PS3 player. We are talking about a console that came out almost a decade ago that has very dated hardware along with the fact that it was never built to handle the capabilities of an MMO of this scale.

The PS4 version is likely going to be superior in every way, shape and form compared to its PS3 counterpart and its something every PS3 player should have in mind when it comes to the future of this game, even if you don't own the console right now.
