I don't see the big deal. It's obvious her actual new contract doesn't really start until after she's done with shooting this movie. They brought her out at Royal Rumble for shock value, to let the fans know she's coming, her contract hasn't really started yet. To me it's no different than doing video vignettes for guys who are coming in, I remember it seemed like Razor Ramon/Mr. Perfect did 100 vignettes about how they were coming to WWF before either actually stepped foot in the ring. This was just a tease to get a pop at the Rumble, set up some intrigue/build excitement for the Women's Championship Matches at Wrestlemania (Who's gonna face who? My bet is Asuka/Alexa, Charlotte/Ronda) and let people know the deal is done and she's on her way.
