I don't see the hype about Britt Baker. To me, she was only interesting when she had Reba, her wheelchair, and Big Swole as an adversary. The only other thing that made her stand out from other women is that Britt was willing to bleed, but WWE probably won't let her do that.
Danhausen's best run was in the original ROH, but he still has a marketable look. I can see him going to NXT, and maybe getting a comedy run. The amount of merch that he'll move will pay for his contract a few times over.
Private Party would be a great pickup for WWE. Their NXT run should be good, somebody there will get Isaiah Cassidy to add some muscle like Marq Quen did, and the brehs will finally lose those horrible bell bottom pants. There are some good teams that PP can feud with, and they'll also have good competition in TNA'S tag division. With PP's fun gimmick, I can see them getting over right away with the NXT fans. If Def Rebel doesn't screw up Private Party's theme song, then "Shots" will ring out just as much as "Whoop That Trick" when it plays over the PA system.
