Yes. James Cameron has confirmed he will make an Avatar trilogy (Like Star Wars, except Star Wars had 6 movies). Sam Worthington(Jake), Zoe Saldana(Neytiri), Sigourney Weaver(Grace), Joel David Moore(Norm), and C.C.H. Pounder(Mo'at) have all signed on for Avatar's sequel. Trudy and Tsu'tey will not return, and Quaritch and Selfridge will almost definitely come back, but haven't signed on yet. Grace is to come back somehow, possibly as a tree, and Quaritch is to be ressurected. Avatar's sequel will not be called Avatar 2 because Jqake became a permanent Na'vi at the end of Avatar. Avatar's sequel is supposed to take place several years after Avatar, and is supposed to explore Pandora's other moons and water life. It is planned to be released in 2014, and might be sooner because James Cameron has held off all other movie plans to make this. Hopefully it will be better then the first!
