What did 360 reach in the end, 90m?
I think 87m is the best estimate. PS3 best estimate is 88m. XB1 will end around 53-54m maybe, PS4 close to 120m.
I'm pretty sure I've mentioned this before, but I think this gen might actually be the one where console sales explode.
Xbox Series will do 360 numbers, PS5 will do PS2 numbers, and Nintendo will stay doing incredibly well.
2020-2023 will quite possibly be the best period for home console sales in history. Switch will do continue to do bonkers numbers into 2022 and PS5 and XBS will have very high sales up to their peaks in ~2023.
Overall I still think Series will be ~60-70m, PS5 ~110-120m, with a total between them of ~180-190m, about 10m better than this gen. Switch will land around 140-150m I feel and its basically a coin toss as to whether its successor will sell 100m+ or 10-20m, as is the way of Nintendo. So I guess a lot of this rides on what part of Switch you count for "this gen" and which side of the coin Nintendo's next successor lands on.
I think there's been a big push for gaming too. First couple years of PS5 I think kick the pants off PS4/PS3 first couple years. The PS2 gen is probably the closest.
PS4/XB1 gen first few years already kicked the pants off the PS360 gen, with the second half being basically flat from last gen. So there's a big difference between those already. It'll be interesting seeing how it goes this time.
