It doesn’t sound likely that Overwatch will come to Nintendo Switch.
Speaking with Gamespot, Blizzard senior game producer Matthew Hawley discussed the possibilities of Overwatch heading to the hybrid system and mobile devices. “There are challenges in running on the platforms that we’re not already on, otherwise we would probably already be on some of those other platforms,” he said.
“We’ll see where things go. Certainly, there is a huge number of people out there who have Nintendo Switch and mobile phones, but right now, the core development team is focused on supporting the live game.”
