So you have no ideia what it should sell just like me.
It is your assumption vs mine assumption.
We know what happened last time in the other thread with these assumptions
Like I said I don't see any evidence of userbase interfering in know popular big IPs.
It will actually move hardware to match it usual sales instead of lose sales due the userbase.
The exception is when there is not enough supply to move hardware.
In that case the userbase indeed slow the sales of these games.
Ragnarok, Miles Morales, GT7, etc should sell the same or even more if launched today exclusive to PS5.
