Advanced development may well be true, as Clayon mentions he has been working on this unannounced mobile game for most of his time at Blizzard Entertainment, which started in 2016. We first began hearing about Blizzard’s mobile focus at BlizzCon 2018, both with the announcement of Diablo: Immortal, and a follow-on press conference in which Allen Adham (Executive Producer and one of the original founders of Blizzard Entertainment) stated that there were new mobile titles in development across all IPs, with more products in development than ever before.
“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. 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.”
