The current gen is the most useless, almost no exclusive great AAA games for it. I brought Series S/X and PS5 and I couldn't be any more less enthusiastic about them.
I would be surprised if PS5 reach 110 mil, especially in the light of PS5 Pro. I think 100 mil is optimistic.

I can agree with this point somewhat, but I think that the gen will last longer than usually. Mostly because the rate of high profile game releases gets lower.
