Blizzard is working on mobile titles for all of its IPs, according to executive producer Allen Adham.
Speaking at a press conference during BlizzCon (via Reddit), Adham confirmed Diablo Immortal wasn't the only mobile product in the pipeline.
"In terms of Blizzard's approach to mobile gaming, many of us over the last few years have shifted from playing primarily desktop to playing many hours on mobile, and we have many of our best developers now working on new mobile titles across all of our IPs," he said.
"Some of them are with external partners, like Diablo Immortal; many of them are being developed internally only, and we'll have information to share on those in the future.
"I will say also that we have more new products in development today at Blizzard than we've ever had in our history and our future is very bright."
Activision Blizzard share price has been on the decline since the launch of Call of Duty: Black Ops IIII which fell short of its predecessors sales by $50 million; the botched announcement of Diablo Immortal sent share prices tumbling even further.
