While I knew AVP 2004 had more than just the one plasmacaster I didn't know there was another model that actually got mounted on a suit. It can be seen in the flashback where the Predators lose and you'd be forgiven for missing it since it's so small and Scar's is the only one we get a good look at. It's almost like a bigger JH.
In the same flashback the scimitars actually got some usage as well. The Predator on the left is using it during this sequence and again since it's so brief you'd be forgiven for missing it actually getting used.
-Edit
Just going through that scene again, a ship resembling the 87 ship is seen docked in the mothership during the flashback. So apparently that' not just a thing with AVP 2010. I guess we do have some sense of scale for the 87 ship.
