According to Heroic Hollywood, link below, Dinsey and Lucas Film are apparently set to announce that Colin Trevorrow, fresh from Jurrasic World, is set to direct Star Wars Episode 9. The announcement will apparently happen later today at the Star Wars Comic-Con panel. I will certainly post up an official confirmation.
Update: With Comic-Con come and gone, and Lucas Film did not make the announcement of the Episode 9 director. However, people in the movie press give some serious weight to the scoops this guy breaks because he has a pretty good track record. So, stay tuned.
