Beasts of War did an excellent job of getting a lot of insight and first looks at what is coming on down the line from Hawk Wargames. There is an interview with David Lewis, where you can see the new artwork for the backing cards, and videos getting a chance to see first hand some of the new models that are coming.
Here are a couple videos that you should see. Then head on over to Beasts of War Invasion 2015 coverage for even more content.
