So another interesting thing is that while Scorpio does have 12Gb of vram, for gaming, it can use 8Gb for games and 4gb is reserved for the OS.

Compared to the ps4 pro, out of the 8gb avaliable, the ps4 pro allows 5.5Gb for games and 2.5Gb is reserved for OS.

I think MS are just playing it safe (for stuff like the dashboard and DVR). There's a limit to how far their RAM advantage can reasonably be utalized in multi-plats, so it's a logical strategy.
