Square Enix support website features a logo for a Star Ocean 2 remake
The logo was found uploaded to Square Enix's official support site at the following URL - though who knows how long it will now remain there.
If you're unfamiliar, Star Ocean: The Second Story is the second entry in Square Enix's Star Ocean franchise, developed by tri-Ace, which originally released in 1998 for the original PlayStation. To this day, Star Ocean 2 is often considered the strongest entry in the Star Ocean franchise, and one of the most popular RPGs on the PlayStation.
Square Enix has not yet officially announced any sort of re-release for Star Ocean: The Second Story, and there are no details about release timing or platforms for a remake or remaster. However, there is precedent for such a release. In 2019, Square Enix released Star Ocean: First Departure R for PlayStation 4 and Nintendo Switch, which is a re-release of the PSP version of the original Star Ocean title with updated character art. While there are no details about this newly leaked version of Star Ocean 2, perhaps we can expect it to fall along similar lines.
Interestingly, today's logo specifically says "The Second Story R", and not "Second Evolution R". Second Story is the subtitle of the original PS1 release, whereas Second Evolution is the subtitle of the 2008 PSP version. What that might mean precisely is uncertain, but perhaps this unannounced re-release might be based on the original Star Ocean 2, rather than its PSP remake, although this is just speculation until more details are revealed.
Oddly enough, in 2015, Square Enix *did* re-release Second Evolution for PlayStation 4 and PlayStation Vita, but only in Japan as a digital title. Although this was only a simple up-rez port at the time, it was never released in English despite the original game being translated, with an English dub to boot.
For moment though, we'll simply have to stay tuned for an official announcement of Star Ocean: The Second Story R at some point in the future.
