I already answered in that last thread as the sales seem to be linked.
This is an extremely early prediction that will likely change as the gen moves on. If the market for PS/XB holds at ~170m.
I give it
PS5- 105m NA 35m EU+others 60m JP 10m
XB- 65m NA- 33 EU+others 30m JP 2m
Just a reminder that this is a simple estimate.
Bonus: No.
