Well, he's half right. PS5 and Series X are not going to slow down Switch at all. On the other hand, the former two consoles are going to sell sluggishly for the first few years. Switch is going to affect PS5 and Series X just like Wii affected the sales of PS3 and XBox360. The Wii sold great for a few years and the other two were sluggish at first. It didn't have a big effect on their lifetime sales. Instead is was mostly a delaying effect on their sales. Switch will have the same delaying effect on PS5 and Series X.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
