Should Humans Still Be Bad Guys Again In The 2nd Film?

[PunkMaister]

Should humans still be the villains by the second film or should another set of villains emerge that forces both Humans and Na'vis to reconsider their hostilities toward one another.
I had quite enough of humans being the villain in the first. I'd love to see more of Pandora explored and a new enemy emerging on the horizon for both groups to deal with. The Cosmos is after all a huge an unforgiving place.

Apparently some have hinted at the appearance of some bug like creatures whether Alien or Native to Pandora itself remains to be seen.
