Who ever's not in the tag title picture will definitely be bumped. So that'll be a rotation between The Usos and American Alpha because The New Day will always be there.
I think we'll be seeing a lot less of guys like Rawley, Mahal, Rowan, etc. and even Ziggler once we get into the summer, Wyatt is firmly out of the Smackdown picture, etc.
I don't think they'll be able to do their PPV quality TV matches like they like to do -- they could, but I doubt it. The thing is that the shows will fly by because they SHOULD have enough quality content and very, very little filler.
