Objectively, the PS4 will have a better 2018 library than Switch. But personally, I would rather have portable versions of the games in a cart (and not a disc). I think most of the PS4 games that I want will end up on the Switch eventually, except for the ones published by Sony.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
