Personally, I think it's just gonna stay pretty much the same. Stephanie will be micromanaged by Vince and Paul will try to get his NXT shit in. We'll see less retarded decision-making and schizophrenic booking, but more bland wrestlers getting pushed (even more so than Vince's WWE)
It will be as bad if not worse. Nothing will really change significantly unless Nick Khan ousts Stepth and Paul/Vince is no longer majority owner. Even then he'd probably just sell to Disney or something so it gets pozzed more.
