Square Enix is speeding through all the classic Final Fantasy games on Sony's Game Archives service. Following the recent release of Final Fantasy V, the company announced today that Final Fantasy VI is on the way too.
As usual, producer Shinji Hashimoto made the announcement at the Square Enix Members Twitter. He did not share a final release date.
Square Enix also has Chrono Cross waiting for release. A release date for this has yet to be announced, but Hashimoto has been publicizing it through videos, so it's presumably not too far off.
