Tri-Ace has started development on Star Ocean 5 back in late 2013 (probably after the launch of PS4) and they are still quite far from finishing up work, as they are at 30% right now, so Square Enix will have to wait to release the game on both PS4 and PS3… unless they rush the devs, risking the final product’s quality. They did manage to publish a whole bunch of images though, so it’s better than nothing. Good work needs time, so we can probably expect the game to show up at the end of 2016…
