Diablo 4 is set to redefine the franchise with a promising array of post-release content. With a commitment to delivering ongoing updates, Blizzard has already shared a roadmap for the game. Compared to its predecessors, Diablo II and Diablo III, Diablo 4 is already poised to surpass them in terms of DLC and expansions. Diablo II and III each received a single major expansion, accompanied by regular patches and content updates. In contrast, Diablo 4 aims to extend its lifespan by offering years of continuous updates and expansions.
Diablo 4 DLC and Expansions Revealed by Blizzard General Manager

Blizzard has confirmed that Diablo 4 will feature paid DLC as part of its post-launch strategy. While the specifics of these DLC packs remain unknown, they will likely follow similarly to Diablo II and III, with expansion packs that introduce new storylines and character classes.
In an interview, Diablo 4 General Manager and Associate Game Director Rod Fergusson and Joseph Piepiora mentioned that the overarching narrative would primarily be progressed through paid expansions. This suggests that significant story developments will be saved for these larger DLC packs.
The developers have also revealed that Diablo 4 will receive new story content approximately every three months. This implies that the game’s story will evolve alongside the free and premium Battle Passes, with minor story progression occurring during the seasonal updates.
During the interview, Fergusson revealed that he is a necromancer main. And when asked about his thoughts on future classes, he avoided mentioning the “paladin” word. While the specific classes to be introduced in future expansions remain unknown, Fergusson’s comments hint at the possibility of exciting new character options to be unveiled in Diablo 4‘s DLC.
On the other hand, Diablo 4 will not feature a cow level. Rod Fergusson stated that including a cow level would be considered “silly stuff” and may not fit the overall tone and atmosphere of Diablo 4.
