[D&D 5e] Where are the campaign settings?

Is WotC ever releasing anything other than adventure modules and novels?

I love the splatbook silence but I'd love to see 5e Eberron. FR, Greyhawk or Mystara might be easy to run straight off the books but Eberron requires a little crunch (warforged, artificers, dragonmarks, etc.)
