Finding money to buy Hulu isn't a problem for a company of that size - if they even decide they want to buy Hulu.
Can they find the money? Yeah, but it comes at a cost to every division Disney has including primarily the park division.
Either Disney is a direct-to-consumer company or they're not. Iger has some tough decisions to make. Forget being a consultant, Wall Street wants Iger to commit to at least 5 years and I expect the board will offer that by the end of the year.
My completely ludicrous predictions:
1. Iger agrees to an extra 3 years on top of his 2. So, 5 total.
2. Iger makes a last minute deal with Comcast to delay the buyout of Hulu for 24-36 months.
3. Disney announces that they're returning to the traditional theatrical window for their releases for most titles including Star Wars and Marvel.
Disney+ streaming will occur at the old premium cable window (same as HBO, Showtime, etc.).
4. Internally, budgets are scaled back. Pixar moves to a one film per year strategy and Pete Doctor is forced out. Brad Bird or Andrew Stanton become Pixar CCO. Kathleen Kennedy decides to retire. Jennifer Lee gets a promotion.
5. Iger starts to sell off assets (undeveloped real estate, Fox's back library, possibly even ESPN, etc.) to "slim" the company, but in reality it's purely for the cash.
6. Josh D'Amaro gets a promotion, but doesn't get the President slot and remains in charge of parks. Maybe he gets to moonlight with Alan Bergman at Studios or they move him somewhere wild like ABC. Ken Potrock gets a promotion to D'Amaro's old job, but doesn't get the title.
7. New CFO comes from outside the company, but former Disney employee.
8. Disney acquires Candle Media, Tom Staggs will return, but not Kevin Meyer.
9. Iger leaves the company after 5 years with Staggs as CEO and D'Amaro waiting in the wings as President.
