They canceled the last Diablo 3 expac. It is doubtful they are making Diablo 4, however they are making a new Diablo game AND REMASTERING Diablo 2.
From what I gather, and this is now my opinion....they are making a "World of Diablo". You can laugh, agree, insult, etc, but I think this is what it will be. They are going to go back to how Blizz Norths D3 was sorta. If job postings and such are correct, it won't be isometric like how Marvel Heroes(I say this because Brevik made this game havea freeroam environment that they were going to do to D3)is. Will be more of how WOW is. It shall be a subscription. I'm sure they will take this great idea and ruin it, disappointing the few people that actually get their hopes up this time. Rather confident that this is what is coming. I could continue on, but I think you guys get the idea by now.
