I think if more people started walking out, that'd turn around really fast. As it is right now, WWE's in reaction mode. They're working to salvage the Biggest Show Of Them All: 30th Anniversary Edition so their biggest gamble in a generation goes off without any more hitches. To accomplish that, retooling the card is more important than dealing with talent who aren't yet in open rebellion. Dealing with the problem in front of them instead of the potential one seems like a valid move for the immediate short term. But again, the dynamics for these problems can change really fast.
