Earlier today an accidental listing went up on Amazon featuring an officially licensed Overwatch themed Nintendo Switch case. It seems manufacturer PowerA listed the officially licensed product of Blizzard and Nintendo, then quickly removed it, but it was to late because thankfully Twitter user Wario64 got us all some screenshots and made the internet world aware.
Although when you have these 2 companies work together our thoughts think that there is a Nintendo Switch Port on its way, it may in fact not be true. It may just be 2 companies helping each other out with some cross-promotion. I guess we will have to wait and see.
