WWE Fastlane takes place on March 11th right between the Royal Rumble and WrestleMania and the SmackDown Live PPV will reportedly be headlined by a Fatal-5-Way match featuring AJ Styles vs. Kevin Owens vs. Sami Zayn vs. Shinsuke Nakamura vs. Randy Orton. Who will be champion when this takes place remains to be seen but it will obviously shape the WrestleMania main event.
John Cena is also advertised to appear but that will presumably be to hype his own match (possibly with The Undertaker) as opposed to being involved in the WWE Championship picture.
Rumour has it that AJ Styles vs. Shinsuke Nakamura is the current plan for WrestleMania and that that will be the SmackDown Live main event. We'll have to wait and see, of course, but things are shaping up to be very exciting for this title (unlike the Universal Championship match which will reportedly feature Roman Reigns vs. Brock Lesnar...again). What do you guys hope to see?
