James Cameron has revealed that 'Avatar 2' will begin shooting in 2013, with the script still being developed.
The first film in what is set to become a fully-fledged franchise was a massive success upon its release, breaking box office records and providing another global sensation for 'Titanic' director Cameron.
He is quoted by the Toronto Sun as saying: "We're not shooting the new 'Avatar' yet. I'm still in the writing process."

Delays have also been caused by the development of new technology to enable film-makers to handle having more Avatars.
"We're underway in the technical development because we're completely re-vamping the whole pipeline, because we've essentially got to do two movies in the same amount of time that we did one in last time," Cameron continued.
He explained that the tech team are doing most of the fiddly work "while I've been off exploring and building subs and diving."
He added: "I'm essentially in the process of writing right now, which will take me through to the end of the year, and then we start pre-production in January."
'Avatar 2' is expected for release in 2015.
