Recently, the tipster @SynthPotato discovered that the Steam page description of "Red Dead Redemption 2" has changed, and it seems to be preparing for the new PS5/Xbox Series remastered version.
It is worth mentioning that "The Elder Scrolls 4: Annihilation" did the same thing before the official announcement of the remastered version.It is reported that just a few weeks after the page description of "The Elder Scrolls 4: Annihilation" was changed, Bethesda officially announced the news of the re-release.
Therefore, @SynthPotato believes that there is reason to believe that Rockstar will soon announce the "remastered version" of "Red Dead Redemption 2", and "Red Dead Redemption 2" with 60FPS will soon be available on modern consoles.
