In a rare official statement on those rumors, Lucasfilm posted the following on the Star Wars website:
We donít normally respond to fan or press speculation, but there is a rumor circulating that we would like to address. We want to assure our fans that Lucasfilm has no plans to digitally recreate Carrie Fisherís performance as Princess or General Leia Organa.
Carrie Fisher was, is, and always will be a part of the Lucasfilm family. She was our princess, our general, and more importantly, our friend. We are still hurting from her loss. We cherish her memory and legacy as Princess Leia, and will always strive to honor everything she gave to Star Wars.
