Where was it part of the terms from Iger that they'd agree to use the outlines? That's the first I've heard of it. Everything I've read, including Iger's statements on the issue were that they all agreed they needed to buy them. That if George Lucas had drafts for new Star Wars laying around, you'd be crazy not to buy them. But, Iger also said they were clear they were under no obligation to use them. Reading between the lines, I always took that as they were buying them to keep them out of the public domain. By making them the intellectual property of Disney, they be less likely to surface years down the road and be touted by certain segments of the fanbase as the "real" Star Wars sequel trilogy. Of course, that's what some are, in fact, trying to say, but that's a difficult argument because the fact that Disney owns them keeps them from, so far, leaking onto the web. My guess is that someday they will be leaked, but it will be in a time, manner, and format of Disney's choosing. Honestly, I have little doubt that if they hadn't been bought by Disney they'd probably have leaked on the web by now with Lucas claiming plausible deniability as to whether or not he was the one who leaked them or someone else who had access to his material.
