This is my gut even though we don't know most of the important stuff, like games, yet. PS5 will win by a smaller margin worldwide. Series X will win by a narrow margin in US and UK. Combined sales of the two systems will be down, because a lot of people will have Switch as their sole console, and will stick with Nintendo for Switch 2. Combined sales 140m.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
