To be clear, this is in the Incubation department, which is for new games. There is a separate Tools Engineer job for Hearthstone and that explicitly mentions Hearthstone everywhere in it and has different general text.
This is also separate from the new First Person game, which is not a mobile title, and the new Diablo game, which is also not a mobile title.
For the curious, without prompting, one of the top Blizzard executives once talked about how great they felt the StarCraft and Overwatch brands were for mobile, so smart money is for this to be one of those two brands.
I'm personally guessing Overwatch, since my guess is that the first person game is StarCraft given who is most likely directing it, but that is purely speculation on my part.
