So in that first thread from 2020 I ticked the 110-120 million poll option. I looked up my post using InternetArchive, and at the time I said my personal range was 107-117 million.
Unfortunately I couldn't find my post for the second, more recent thread. But I can see I ticked the 120-130 million box, so I'd obviously revised my estimate up slightly.
I think PS5 & Xbox Series will sell 175-185 million combined by the end of the generation. The question then becomes the split. Right now PS5 has 58.5% market share. I think the next few quarters it's going to increase that share quite significantly, before some of the increased market share is eaten into by Xbox Series in the middle and towards the end of the gen. For now I'll go with a 60:40 split, which would put PS5 at 105-111 million. I ticked the 110-120 option because I think the higher end is slightly more likely than the lower end.
