There's a bigger picture here too. If AJ drops the title to a Bella it will feel like a reality TV moment, a set up, manipulated X Factor style. If she loses to Nattie, who has been portrayed as an underdog on Total Divas and is a face and the best wrestler of the bunch and ultimately deserving of it, then it will feel like a WWE moment. (Does that make any sense in a not "IT'S STILL REAL TO ME DAMMIT!" way?)
Could whomever wins the title be seen as an indicator of WWE's feelings towards the division? A Bella: the divas are for publicity only, Nattie: the divas can wrestle and that matters, Naomi: we believe in the new generation?
I'd like to see Nattie win and have a decent run defending against AJ and the Bellas.
