I swear I read that article a few weeks ago and it was reasonably well edited at that time. You need to post links to the Internet, not to teh intarwebz.
Anyway, Indy is part of the deal. Who knows? Maybe they'll get cracking on a sequel.
My understanding is that Ep 7 is working from a "treatment" by Lucas, and that he gets Creative Consultant credit on everything (of course) but it doesn't sound like he'll be that involved. At this point, Disney/Pixar's track record is a lot more solid than Lucas' is. I really have trouble seeing this as anything but upside. It may turn out that we get crap movies, but that's what we would've gotten under Lucas, anyway.
