#3 Smackdown Live Women's title
Let's be honest here.
The WWE Universe wants to see Asuka finally get her crowning moment and win the Smackdown Live Women's title at TLC. In all honesty, anything less than that will likely drive fans into a rage and make them consider giving up on the product, which is why the company is likely to make the safe decision here.
Interestingly enough, Ronda Rousey's presence is also shrouded in the match and could be WWE's way of switching the title to Asuka without making Charlotte and Becky Lynch look weak in defeat. In fact, between the threats that the two parties have lobbed at each other and the momentum that Asuka has right now, some kind of interference seems almost certain.
Whether it happens or not is up to WWE, but its hard to imagine that they wouldn't pull the trigger on an Asuka championship reign if they have everything at their disposal to make it work.
