2 weeks before Mania, with no build or storyline to the match w/ Asuka

WWE tweeted hours before SmackDown that there was gonna be a 4-way #1 Contender's match that night to see who would face Asuka at WM, so clearly this was a last minute decision.

The only reason to do this is if you are planning on unifying the titles and want to get it done at Mania. I really hope they do this (in fact, I wish they'd unify the WWE/Universal titles, and the Raw/SmackDown Tag Team titles as well) but I'm not sure why they would suddenly decide to do this, last minute, at this time. The only reason I can see them unifying the titles would be because they are putting the women all on one show.
