Via Fields Of Blood (and then La Taberna De Laurana and The Shell Case)
Update - A few things new to mention since this went up. The internet seems to have exploded by DA articles.
Firstly the lovely Codex cover
and also the price list, that contary to internet opinion lists the author as Jeremy Vetock (which I have mixed feelings on, as the Skaven fluff he wrote for their army book was unreadably bad) and gives a sneak peak of Hobbit Eagles, and the arm of something big.
Lets get down to it, starting with the Deathwing.
Note he's Finecast. For me the pose is a little too squeezed in. The legs don't seemed braced far enough apart. I like the detail though.
It would seem that these are a specialist Deathwing unit, and they look pretty damned good, certainly going to be stealing parts from them, especially as they come in a set with these... (look at the legs)
Sadly compared to the Knights these fall a bit flat. I think we'll see the Knights parts mixed in far more liberally with these models. Really wish we'd got a better view of that axe. The sword looks very good though, and I think these command parts will see a lot of use in other forces.
The Ravenwing also get there fair share of stuff...
But enough of the ground forces, time to look to the skies.
Well, these are the first Space Marine flyers I've actually liked. Still a bit boxy, but moving in the right direction. Apparently they're called Dark Talons
