Personally, I would like to see the sequel, some decades later, where a now-united Federal Earth decides to screw this Hopey Changey bullcrap and sends in the Mobile Infantry to get the Dilithium (which is what "unobtanium" actually is, Cameron just can't come out and say he stole the idea from Trek) to fight the Bugs.
"All right, Troopers! We're going to turn this thing into a really beutiful, but poorly written movie! Let's kill some Thundercats!"
