This video shows off some new artwork as well as a real good look at the two new models in Shield of Baal Deathstorm. Its an excellent look at the new boxset, and the video is very nice in comparison to some of the previous ones we have had.
Here is a link to the video. Note that the boxset is sold out on the US GW webstore, but still available elsewhere. The boxset will also be available at GW and local stores on release day.
