From what I've seen/read so far eps 7-9 will pretty much be lucasfilm productions distributed by Disney ( with a different person in charge of lucasfilm, which would've happened anywaymf)...Lucas had already decided to retire and nominated Kathleen Kennedy as the new head of lucasfilm before the sale had even occurred so I'm pretty sure the franchise will be in capable hands as long as Lucas ( the goitered fuck) has minimal input on the new trilogy. I wouldn't worry too much at this stage. Seems like lucasfilm has control on who makes ( as in writes,directs, stars in etc) the new trilogy. Still doesn't mean it's gonna be good but ill wager they ain't gonna put tinkerbell in it or anything...as long as lucasfilms make money, Disney will treat em with the same autonomy as Pixar.
Disney have had some decent talent working for em in recent times anyway, like joss whedon and brad bird, so I would have more faith in Disney than lucasfilms...
on topic, that video is far more entertaining than any single scene in rotj!!!!
