Non-competes are an interesting space. Especially because California, where Disney is headquartered, doesn't enforce non-competes. That being said, with these multinational corporations, it's hard to figure out which laws apply where.
Jeff Bezos won't ever happen. He wouldn't leave Amazon (he did found the company) and Amazon has aspirations of becoming Disney (along with every other company it seems like). I really can't buy the idea of Disney grabbing a pure tech CEO. You would need somebody with sufficient media experience too. The only true tech / media company I can think of is Yahoo... and I'm not thinking Disney is rushing to grab anybody heading that ship.
That being said, I'm convinced it'll be Sheryl Sandberg. She's never going to be CEO at Facebook, she's on Disney's board (has media experience), and she's from a tech company. If Disney wants to prove it's partially a tech company, it'll need to pick somebody with tech + media experience.
