It's really hard to say how many. I wouldn't be shocked if this number turns out to be 0. However I am going to be bullish and say it will outsell Diamond/Pearl. If it can outdo Sword/Shield then I will definitely be shocked.
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
