Blizzard have taken to Twitter to tease their entire audience on Diablo 3 coming to the Nintendo Switch. A gif was released showing a Diablo themed night light being turned on and off.
The post from Blizzard certainly is confusing and does come across as slightly random, but when looked at as a marketing post for a future game release the picture comes together much more nicely. The post captioned "Sweet Dream" features a gif of someone switching on and off their Diablo themed night light, this could suggest that Diablo is coming to the Nintendo Switch.
On the other hand, this post could also be interpreted the opposite way, as the caption says "Sweet Dreams" this could also suggest that the Diablo themed night light is just a random post by Blizzard. This side of the debate is backed up by a post made by South Park that said "Nin-ten-do. I'm coming. I'm coming, Nin-ten-do #blizzard2017." Everyone thought that this meant a South Park game was coming to the Switch, unfortunately it was just a 'joke' post that never had any further meaning.
