I think it will sell around 2.5 million, but anything north of 5 million would be a surprise to me. Switch versions of games tend to be top sellers for franchises. Plus at least for me, I don't see a lot of great single player games coming out the rest of the year. The games still coming out this year that I will purchase include Metroid Dread, Tales of Arise, and Horizon Zero Dawn if it comes out this year. I'll probably get Kena as well assuming the reviews are decent. There are a few other games that may sway me but only 3 for sure purchases.
