You can purchase Diablo III for Nintendo Switch right now if you live in the UK, that is if Cool Shop has it in stock, which they don’t. They do have a price listed however, at £47.95. That converts to $67.84 USD, though chances are it would be sold in the west at the flat price of $59.99. That is if Diablo III is actually coming to Switch.
As of now, the game itself has not been announced as coming to Switch and the only reports on that possibility are twitter based rumors and a potential “hint” from the official Diablo twitter account, though denied that what they posted had anything to do with Nintendo Switch. For reference, it was a short clip of them turning a Diablo III themed light switch on and off.
At this point, with retailer listings now popping up, many are assuming the title is on its way to Switch. All I know for certain is that Diablo III isn’t exactly the one blizzard game I am waiting for. Call me up with Overwatch gets announced for Switch!
