The company is in the middle of the planned Microsoft merger Diablo 4 could prove to be the final game released by "Old Blizzard," and there's a lot on the line to deliver the experience they've always wanted, especially because, in the years following Diablo 3, other games that are in the same genre, like Path of Exile, have been able to challenge Blizzard's looted crown.
