i think that humans will come back, but with allies from anther species to help. Maybe another home tree, but i think that would be a little stupid. Another scenario would be that humans came back and won, in witch case it would be about some kind of rebellion.
Actually how about this for a sequel.
Since there is now a human being who has been totally transferred to a navi body. They use what was left behind by the humans go to earth and kick butt being joined by the freakazoids from peta. :duh:
The cold reality is that the human race would come back and simply wipe out all life on the planet with an orbital barrage, then they would come in and harvest the now dead planet.
