The Switch will become the best selling console of all time. However you won't be able to tell it by 2018's performance. 2018 will be mostly ports and a few new 1st party titles here and there. In 2019, there will be Pokemon and more 3rd party exclusives. That is when Switch will really start to take off.
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
