We have seen a solid release list for the Horus Heresy and it appears that the plan for moving forward is main releases every year that will include a focus on two legions. Im hoping the release schedule is a little faster than yearly, but this looks solid to keep the game moving.

I have some information again, but this time it seems a lot like the last one.
HH will get yearly main releases with two featured Legions focused on (which doesn't mean other legions do not play a role - See SoH and IF, also WS, BA, EC and WE).
Every main release will have a box set and a warzone/campaign book. With every main release, the focus will rotate to other Legions and another campaign or operation.
Within those months we get regulary releases like for the two other main games but also specific stuff for those Legions.
