I'm still forming my opinion on the idea, but I'd like to point out that all the articles "confirming" it point to the same article on a site you've never heard of using no quotes and a single unnammed source who "works close to the production".

Even EW, who got the quote saying he'd rather just be in the audience and wasn't interested, immediately posted a link to this site and said "well, I guess he changed his mind" without putting up a disclaimer that no one has spoken to JJ since the "announcement". People are saying that the LA Times saying "sources confirm" is confirmation. Note they don't say "OUR sources confirm" or what those sources could be. They don't even have a link to the original article!

I'm wary, especially so soon after reading this:

If it is true, its a leak that couldn't come at a worse possible time. The first comic lead in to Star Trek Into Darkness came out this week, the "Countdown" is literally beginning. Now that news is overshadowed by him abandoning the Trek ship for Wars.

I'm unconvinced, even with Jett Lucas and Bob Orci making it sound like its definitive.

I also can't imagine what sites like TFN will do with the complete secrecy JJ would bring to a Wars movie. They'd get so frustrated not knowing who the villian is!
