The reason is that the medieval RPG will appear in Xbox Game Pass this Friday, February 13. It is logical to assume that the release on PS5 will coincide with this event.
The rumors are being confirmed: last week, a leak from the PS Store pointed to a "PS5 version of Kingdom Come: Deliverance" with improved graphics, 4K resolution, higher frame rates, and updated textures. There has been no official announcement yet, but given the game's appearance in Game Pass, it seems almost inevitable.
Additionally, it is worth noting that Kingdom Come: Deliverance 2 marks its first anniversary as early as February 4 — the events are lining up logically, creating the perfect moment for an updated release.
