They won't.
People keep overlooking the aspect that the reason those amounts are as high as they are currently is because Turner and Disney were essentially competing with themselves during the last round of negotiations. Even the NFL didn't get the exact amount that they were originally looking for as the networks balked at their asking price.
It's going to be the same go around this time with Disney and Turner competing against themselves unless an Amazon comes into the fold and makes a bid. That isn't likely though as they don't have the infrastructure in place to compete with the sports networks right now.
