A rumour has emerged from Neo Seeker that Blizzard is hard at work on Diablo 3 for the Nintendo Switch. The site says the following:
“Blizzard is looking to implement local play with multiple Switches, allowing you to team up for local co-op action as you run around Sanctuary to stop Diablo.”
Of course this is just a rumour at present but the site speculates that the announcement could come at Nintendo’s E3 event in June, or Gamescom and Blizzcon later in the year. The game is speculated to come to the Nintendo Switch early 2019.
