I think Josh will probably be fine - more of the same, but I am not sure about Dana as "Chief Creative Officer" - I mean, is she really a creative? That's the kind of title that goes to a person who they want to be in charge, but maybe doesn't have the business background - like Dave Filoni at Lucasfilm or Jennifer Lee at WDAS. It's nothing against Dana, but she seems to be more on the business side. I know that in Hollywood that line can get a little blurred, but CCO just seems a little off for her.
I do hope Josh does a great job. I know last time they promoted the Parks head things didn't exactly go too well. D'Amaro is at least more affable and seems well-liked. I don't expect him to usher in a new era or anything, but hopefully he lets his people work the way Iger generallyd. If he does, then the real question will be who succeeds D'Amaro at the Parks division?
