Blizzard is measuring interest in a second expansion toDiablo 3 through player surveys reportedly circulating now.
NeoGAF user Nirolak posted a screenshot of the survey question, which asks "How interested would you be in playing a second expansion to Diablo III?" then lets respondents select from "Not at all interested" to "Extremely interested". The rest of the survey reportedly asks about player satisfaction with Diablo 3 and other games.
Blizzard told Videogamer.com in March that it was "still evaluating" whether to develop more expansions for the action RPG.
An extensive Diablo 3 update went live earlier in April, covering bug fixes and updates to features including classes, crafting, items, monsters, quests and the UI.
CVG's 7/10 Diablo 3 Reaper of Souls review concluded: "Offering rebalanced systems, increased level caps and a new class, Reaper of Souls is worth one last crusade if you can stomach the price."
Diablo 3 Reaper of Souls sales topped 2.7 million units in the expansion's first week of availability, according to Activision Blizzard. In November, Blizzard said lifetime Diablo 3 sales across all platforms had reached 14 million units.
