While the current version of Diablo 3 is a great deal of fun, the numerous technical errors and design decisions that have plagued it throughout the first few months have unfortunately prevented it from becoming something truly special. And so, while Path of Exile continues to push the boundaries of what an ARPG can accomplish, Diablo 3 has mostly been left in maintenance mode.

There is a chance this will change in the future, however, as Blizzard has just recently revealed that there are currently multiple Diablo projects in the works. What exactly these projects are, and whether any of them are actually Diablo 4, they have not clarified. What I can tell you is that we'll be getting more information about some of these projects later this year, most likely at Blizzcon.

Personally, I doubt it's going to be a Diablo 3 expansion as there is far too much resentment towards the game for Blizzard to be able to turn that ship around. So if they're actually working on a 'proper' Diablo game, I do believe the likelier scenario is that they're taking everything they've learned from Reaper of Souls and putting that towards Diablo 4. Naturally, this is just pure speculation on my part, but it does seem to make sense from a business standpoint given how well Diablo 3 sold despite all of the controversy.

As for the rest of the projects, they could be anything from comics, books, to even different types of games set in the Diablo universe. That last part is pretty much just wishful thinking on my part, but it certainly would be interesting to explore the wonderful Diablo universe from a more grounded perspective. Whatever the case may be, I would highly recommend keeping your expectations in check as even if the greatest game in the world was hiding behind this little teaser, it will still be a couple of years before it sees the light of day. 

Once more details get revealed I'll make sure to let you know, but until then I'd suggest you go and give Diablo 3 another try, especially if you haven't played it since the early days. It really has improved for the better!
