Dark Angel images are leaking now from both Warhammer Visions and the next White Dwarf. The new Interrogator Chaplain is $30 and soon (next week?) to be Pre-orders according to the Warhammer Visions where the model is already being advertised. Also of note that we are seeing grav weapons on Dark Angels, so its a very likely addition and an indicator that indeed a new codex is coming, most likely with the established order of things, datacards and a painting guide.

Paint Splatter teaser is "Dark, but not black". Just insert an "Angel" and be happy.
