Is there a PC release date?
No. Rockstar's official GTA VI website and support pages currently list only PlayStation 5 and Xbox Series X|S. Any precise PC date is speculation until Rockstar makes a separate announcement.
StatusA PC version of GTA 6 has not been officially announced.
Are the system requirements known?
No official minimum or recommended PC requirements exist. Hardware tables published before a PC announcement are not Rockstar specifications.
What would count as confirmation?
Reliable confirmation would be a Rockstar announcement, PC appearing in the official platform list, or a GTA VI listing in the Rockstar Store.
