If Disney sold off everything but the main studio, it couldn't compete truly with everyone else in the entertainment world. It needs scale to stay relevant, hence it needs more than the core Disney brand. That's what ABC, ESPN, Pixar, Lucasfilm, Marvel and Fox all provide, and they're all complementary assets. Parting with any one of them would be a short-term gain for a long-term loss. Especially because Disney's debt load is only half of what it was when the ABC deal went through in 1996. If the company could get through that with ABC being mismanaged for so long, Eisner making so many poor decisions at the end of his tenure, and the stock price stuck in the 20s by that point, it can easily get through this with more than one brand.
It's also so absurd that Avatar missing North American estimates by a measly $1 million is enough to call the results "tepid." Since when is $550 million worldwide in the first four days "tepid?"
It's absurd these dishonest vulture want to force Disney into a corner to shed core assets.
But if things get hairy, after buying out the rest of Hulu from Comcast in 2024, integrating it into Disney+ and the like, it could always sell it all to Netflix as an exit strategy. But that's only if all else fails. And I don't think it will.
