VGTimes reported on November 2 that the X account PlayStation Game Size, which monitors changes to the PlayStation Store database, indicates GTA 6 could require PS5 system software 14.22.00.00 or newer. No verification was offered, and the report itself calls the information unofficial.
Sony released PS5 update 26.07-14.22.00 the same day, with security fixes it did not detail. Rockstar's website currently lists no minimum PS5 system software for the game, and neither company has commented on the claim.
Why it matters: if accurate, PS5 owners should update their consoles before the November 10 preload so the install is not held up. Treat the version number as unconfirmed until it appears on the PlayStation Store page or Rockstar's support site.
