Early 2021.
I think they are going to aim for late 2020, but it will get delayed to late 2021. Personally I think this is a better date anyway. Breath of the Wild basically dominated the gaming discussion for the first half of 2017, because it was easily the most significant release at the time. They should do that again with BoTW2. This game deserves to get about a half year of many people's attention. Let it stand out and shine again.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
