Well after what happened to her with her arrest and stuff, they aren't going to give her a massive push right now.
I say she's going to be a bit like Alicia Fox, someone who might not ever be the main focus of the Diva Division but she get her chance somewhere down the line, gets a run with the belt for a while and goes up and down the card. She's not going to be quite in the realms of the Bellas, Paige, AJ really. I wouldn't be surprised if she's let go in a year or two either.
Emma wont be let go, she is Paige's bestfriend. Plus the wwe would be idiots if they don't do a Emma and Paige feud on the main roster seeing how well they work together, their feud in NXT was.
