Given the chip shortage situation, it is guaranteed that Switch will be down YoY. I also think PS4 2014 vs. PS5 2021 is going to be very close right until the end. I can't tell which one is going to come out on top, but I do think PS4 2014 will continue to close the gap each week.
Out of the current consoles, the only one I see "winning" in your face-offs is X|S 2021. It really is selling so much better than XB1 2014.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
