Blizzard should call Diablo 4's next season Diablo 5 because the changes coming are so fundamental and different, that it will feel like you're playing a whole new game. After months of teasing a massive update to Diablo 4's core design, Blizzard used today's Campfire Chat steam to walk through season 4's rework—which will be permanently in the game from then on—to loot and many of the game's other core systems throughout a nearly two-hour stream. The changes touch almost every aspect of the game, which is probably why the stream opened with game director Joe Shely defining the most important aspects of Diablo 4 as the decisions you make before combat and the ones you make in between to set up what's in store next season. Will it be enough to revive the fanbase or is it already too late?
