The New Warhammer World Campaign has new formations and dataslates, and the campaign rules have been rather fully revealed. The interesting part is they include a lot of dataslates for Khorne Daemonkin.

Of course I find that I am liking the Imperial Formations better, but so much focus on the Khorne Daemonkin codex gives me great hopes for the other Daemonkin Codices that are rumored in our future.
The Forces in Blood Oath- Each gets a dataslate formation.
