The first add-on pack of Warhawk, named Omega Dawn, has been announced quite recently, but thanks to our friend TTP we already have a first video of a new map, and as you'll be able to see by yourself he certainly knows how to handle these ships!
Update: And here is the second video, showing the brand new and interesting dropship in action.
Update 2: 2 more videos added, one showing the dropship moving another vehicle around, and the other detailing the new map.
