Moments ago, Jonathan Rinzler, Star Wars scholar and Lucasfilm historian, was asked today on his Reddit AMA if Boba Fett survives the Sarlacc:
"Yes, he does. I have been in meetings with George [Lucas] where he confirms that Fett survived. If it comes from George then it's true!"
(Helmet nod to Matt at Jedi News? for the head's up!)
This confirms something we've heard -- but less in the spotlight. Back in 2012 at Celebration VI, Lucas was recorded without his knowledge at an exhibit of Boba Fett fan-made helmets. In that video and our news report, Lucas says Boba Fett did not die.
