Square Enix has confirmed that Final Fantasy XIV: A Realm Reborn players on PlayStation 3 will be able to upgrade to the PlayStation 4 version for free.
Producer Naoki Yoshida told Famitsu that the upgrade will actually be a transfer of log-in rights, and once a player upgrades they will be unable to access the PlayStation 3 version anymore. This means that if you wish to play both versions of the game you will have to buy a second copy.
Yoshida added that the PlayStation 4 version runs in full 1080p resolution, and that a keyboard and mouse can be used to play. According to him, the PlayStation 4 version should be indistinguishable from the PC version. Final Fantasy XIV also supports remote play on PlayStation 4, but Yoshida advises against it as the chat windows will be too small to read.
A beta test for the PlayStation 4 version will begin on February 22, 2014–the same day that the PlayStation 4 goes on sale in Japan. Earlier this week Square Enix re-enabled digital purchases of the game, following a halt on sales due to server overcrowding.
