Roadmap: What we can expect from HW2?

Hey Halo Wars 2 Product Management Team,

do you have a roadmap or something else, which Shows us what we can expect from Halo Wars 2 in the (near) future?
I am thinking about buying the game for PC and wanna know what there will be added to it.

Thanks in advance and best regards

That’d be cool, kinda like the images they gave us for Halo 5. Even just giving us random pictures and a title would be nice.
