There is indeed an upcoming Diablo game.

The game is not Diablo 4, nor is it a Diablo 3 expansion.

The game "plays differently" than previous Diablo games. In this regard, he mentioned that it does not play in the traditional top-down Diablo style.

So, I have a relevant story to tell.First off, I apologize that I don't have any actual proof for this story. You'll have to take it or leave it for what it is. Second, I feel kind of bad posting it, because I don't want to get anyone in trouble or anything like that.Here goes:I work at a restaurant in California. About two months ago, a customer came in wearing a Blizzard Entertainment hat. In passing, I mentioned that I thought his hat was cool. The customer mentioned that he worked for Blizzard (I'd rather not provide any more information beyond that, as I don't want to get anyone, including the customer or myself, in trouble). Proof for working at Blizzard was thoroughly convincing, however.Upon mentioning that I was a huge Diablo fan, the customer revealed a few things regarding the next big plans for Diablo. Here are the few key points worth mentioning:Upon asking more questions, the customer requested that I ask no more and be patient. In actuality, he never did really request that confidentiality be maintained on the subject, though I still feel a bit awkward for posting this. Once again, I apologize that I don't have anything to show for this scenario, but I guarantee that it will be confirmed come the new project's announcement.So, in turn, I think the most intriguing information that I have to give is that the game is not what most Diablo fans would be expecting, and rather, is a stand-alone game with completely different game mechanics than previous Diablo games. Again, take it for what it is, but I think you'll be surprised when the new game is announced.
