-While AJ Styles did lose the United States championship at the Hell in a Cell pay-per-view event, he is being penciled in for another headlining run on Smackdown as a challenger in the near future for WWE champion Jinder Mahal, which is why Styles was put into a triple threat match where he could lose the title without being pinned.
It hasn't been decided yet whether to try to get another pay-per-view out of Mahal and Shinsuke Nakamura, but Vince McMahon made the call to get the US title off of Styles as soon as possible so that when he decides to program Mahal and Styles together, only one of them is a champion heading into the feud.
This is why the Hell in a Cell United States championship match was changed to a triple threat on such short notice. Styles was originally scheduled to retain at the event.
-Jinder Mahal continues to earn high marks for his improvements since becoming champion and McMahon has toyed with the idea of him keeping the title all the way until WrestleMania. However, with the WrestleMania card still an afterthought at this point beyond Brock Lesnar vs. Roman Reigns, who Mahal would face hasn't been discussed much.
-Survivor Series is still two pay-per-views away and traditionally that's when McMahon gets more aggressive in starting to formulate the WrestleMania card, but with Kevin Owens vs. Shane McMahon having just taken place, a program originally conceived as a WrestleMania match, the Smackdown brand has nothing in particular being saved at this point for WrestleMania.
Over on the Raw side, the only other WrestleMania match that has even been discussed lately is an idea for Dean Ambrose to go heel early next year to work a WrestleMania program with Seth Rollins.
