Is this after aggressive optimization? Size inflation for AAA games has truly reached new heights. If it had to be released via physical media that would require 3-4 BD discs at minimum.

I've been on a retro gaming binge lately because I strongly believe the constraints & limitations of older platforms yielded a better product imo.

It is just speculation at this point, no official numbers yet. Some leaks have suggested a size about that, and it seems to be in-part corroborated by the physical editions being download codes.
