Whether they do it now and share the profit with Fox or wait three years and keep it (mostly) for themselves, I think Disney will inevitably restore the original versions.
Just not convinced though Fang that big corporations think like that i.e. sitting on a product for three years; their bean counters are (rightly) going to want to maximise everything. Three years down the line, they’ll all be in new roles anywhere.
Don’t they want as much as they can, as soon as it’s possible feasibly?
