Currently PS5 sells less than PS4 and it seems that PS5 Pro doesn't give a big boost in sales. If Microsoft releases their new console next year, I can see Sony following in 2027, because PS5 already peaked in 2023.
Sure, we'll get GTA VI, but I expect just a temporary boost for a couple of weeks. Nothing comparable what Covid did for PS4.
I expect PS5 to sell something between 110 - 115 millions after all is said and done.
