Obviously they will have to pay cash for the outstanding 39% of SKY (which I said in my initial comment), I'm just saying that Comcast has the ability to use the Marvel rights (as well as 30% of Hulu) as additional leverage in a deal.
Honestly, this is likely the only opening Disney will have to get the Marvel rights back from Universal (not just park but also Hulk/Namor). As has been stated before many times; there is no reason for Comcast to negotiate Marvel rights with Disney and no reason for Disney to overpay for those rights. SKY and HULU being much larger deal points could instigate discussion.
