I don't think the situation is that bleak. As of 9/30/14 TWDC had $3.4B in cash and they are generating close to $10B in operating cash flows every year (source = TWDC 10K
). There's no cash shortage there.
The new management team will not have any need to sell off components of the company if they don't want to. What they will need to decide is what to do with all the cash thrown off by the various business units. Whether it's reinvestment in the current business, acquisitions of new businesses or returning capital to shareholders they will have to find the right mix. Returning capital to shareholders is not actually a bad thing, but the recent trend of stock buybacks was excessive. There is certainly no argument to be made that the DIS stock is underpriced or a bargain anymore so continued aggressive buybacks don't make much sense.
IMHO Disney is well setup for long term success if the right person is selected to replace Iger. Assuming the weatherman doesn't get another contract extension beyond 2018 and there isn't some major economic downturn the new CEO will be inheriting a company operating at a high level with a number of recent successful years. It won't be like Iger taking over for Eisner after a downturn or Eisner taking over as the company is about to be split up and sold in pieces. This may make dramatic change more difficult since shareholders are pretty happy with the status quo. A strong leader needs to step in or you can almost guarantee there won't be much of a change.
