Rich Ross has stepped down as chairman of Walt Disney Studios with some sources saying it was Ross' decision and others claiming it was a firing. No current news of possible replacements. I've scanned a number of news articles and while many are including a photo of him at the Muppets Walk of Fame ceremony, none are citing "The Muppets" as a reason or casting them in a negative light. Those that have mentioned The Muppets in the context of the article are citing The Muppets as one of Disney's successes under his tenure. Ross was very supportive of the Muppets and of course it was under his tenure that the Segel film went from just being talked about to actually produced. Hopefully whoever takes his place shares his enthusiasm about The Muppets as a Disney property since in a company like Disney, how much weight and support put behind them depends on who's in charge of them at the time.
