I personally don't think so. Cameron's had a wonderful streak with Titanic and then Avatar, but there won't be a gimmick like 3D to really propel Avatar 2.
To be honest aside from "Sully" ... I can't even remember a single character's name from Avatar. I doubt most people can, and the only reason I remember Sully is because is sounds like Scully (aka: Gillian Anderson from the X-Files).
I think Avatar honestly is Cameron's weakest film too. Terminator, T2, The Abyss, True Lies, and yes, Titantic are all better movies.
