What is confirmed
The space requirement is up to 212 GB on supported consoles. It is not a claim that the final installed files have the same size across PS5 and Xbox Series X|S.
How to use this information
Free sufficient space before pre-loading and follow Rockstar and console-store instructions if the installation needs additional capacity.
What not to assume
Do not repeat unverified PC specs or promise a uniform 212 GB finished installation.
