Is there a Blizzard franchise you want to carry around in your pocket? Obviously, you can already play Hearthstone on your phone, but perhaps you’d like to play a version of Overwatch where you’re tracking down and shooting Omnics in the real world, or perhaps a version of Diablo allowing cross-client progression. Whatever the case may be, we don’t know that another mobile title is on the way, but considering the company is hiring for a new mobile software engineer, it seems likely.
While it’s unlikely to be a completely new title, there have been rumblings for a while that either Overwatch or StarCraft would lend themselves to mobile offerings. That could mean it’s one of those two, or it could be another crossover property like Heroes of the Storm. Or even a mobile port of the original StarCraft (stranger things have happened). It’s all speculative at the moment, but if you enjoy playing on your phone, it’s all positive speculation.
