I think it will sell about 18 million, so 4-5 million less than Zero Dawn's lifetime.

High price, PS5 shortage, not being huge enough a jump over Zero Dawn in perceived quality, and getting overshadowed by other games may translate to a decline.

This reminds me, when this game was first announced, didn't people think it would be the next Miles Morales? As in more like a 1.5 jump instead of a 2.0 jump? Like Splatoon 2 was to Splatoon 1. I feel like I heard a lot of people say things like that back in the day. If that perception still exists, then many may skip it that would play it if they viewed it as a full sequel.
