Star Wars Underworld posted so rumours about where episode 7 will be shot:
An inside source has confirmed to us that shooting for Star Wars Episode VII will be taking place in various locations across New Mexico. This has long been rumored but our source has confirmed to us that Disney has signed a three year deal to shoot the film in New Mexico and will be opening up a production office there in January.
Rumors of the New Mexico shoot have existed for some time now, and with production on the film set to be in Spring 2014, opening up a Production Office makes sense. New Mexico is also home to some very interesting landscapes (see image above) to could lend themselves very well to a Star Wars planet.
As always, it’s not official until Disney or Lucasfilm says so.
