Yes, my mind is as blown as yours is. Let's start off with what we do know so far:
You might not be able to put a price tag on beloved franchises like "Indiana Jones" and "Star Wars", but apparently 4.05 billion dollars is in the ballpark. That's how much the Walt Disney Company shelled out for all of Lucasfilm's holdings including special effects house Industrial Light and Magic and Skywalker Sound, and presumably their game development arm, Lucasarts. The whole thing will be overseen by Kathleen Kennedy, who's currently the co-chairperson of Lucasarts and will join Disney as president of Lucasfilm.
The other big news is that "Star Wars Episode 7" will be in theaters in 2015, with plans to release a new film every two to three years, according to this post on the Walt Disney Company blog. Of course, no word as of yet what time period "Ep. 7" would occur, but there's a whole host of expanded universe novels to pick from if they want to keep mining the post-"Jedi" universe. This is in addition to new "Star Wars" properties including the in-development game 1313 and the animated series from Seth Green and Matt Senreich, "Star Wars: Detours".
This follows George Lucas' announcement earlier this year that he was retiring from making blockbuster films.
