Here's my thoughts on this list:
Ghost Hawk. Already known and pictured. As Redmao said, I too am happy to see windows. Overall this a a great update on the original. I also like the Liftticket figure. A good use of other figures and new parts.
Arctic HISS. Finally a HISS repaint that isn't blue or crimson. Of course it is a wait and see on the paint scheme, but at least it is a different idea for the mold. I am concerned about the "Arctic Driver". This better not be a simple white repaint of the HISS Driver mold. I would prefer a "new" frankenjoe Cobra arctic soldier, or a reuse of maybe the Snow Serpent mold.
CLAW & FLAK. Again with the CLAW? This mold is fine, but nowhere near as good as the original. The FLAK is a good toy as well, but I wouldn't have put this in my top ten of what I would want to see this soon. This set is obviously going to be sold on their figures. A Stratoviper and Outback!!! I love the Stratoviper and can't wait for it. Outback is a good figure as well, and one that is fine for a vehicle pack rather than a single card.
Stinger. This was confirmed a while back. I am anxiously awaiting this vehicle. I was kind of hoping the Stinger Driver would be rereleased with the vehicle, but I guess it is wait and see for the Stinger Commander.
