I'd love to see MACO uniforms (and their weapons) in the game as well. Since they're coming out with a TOS-themed pack (with new outfits, bridge, and ship interior), hopefully they'll eventually make one for ENT, including the MACO uniforms.
I would love to have a Porthos pet now, though.
(Of course, if/when they do make another ENT-themed pack, I'm guessing it will be after they go through and do packs for the other shows first. Which would be cool for me; I can wait.)
