While the exact finish for Roman Reigns vs. Braun Strowman has not been decided yet for tonight's Payback pay-per-view, most of the ideas revolve around seeing up a rematch that would main event Extreme Rules in June. Of course with it being Extreme Rules, the rematch would have a stipulation.
There had been speculation based on the recent angle with the ambulance that the Payback encounter would be made an ambulance match, but Vince McMahon decided that with the House of Horrors match between Randy Orton and Bray Wyatt already scheduled for Payback, and with Extreme Rules by its very nature guaranteed to be full of stipulations, that it was better to hold off on the ambulance stipulation for Payback.
Other gimmick matches have been suggested for Extreme Rules, but an ambulance match is the leading idea at this time.
As for the House of Horrors match, the hologram idea discussed last week has been thrown out the window as Vince ultimately made the call that the hologram technology was just way too expensive.
We can confirm that WWE pre-taped footage of Randy Orton vs. Bray Wyatt this morning inside a carnival-themed house to air as the first part of the House of Horrors match. As noted on Raw, the bout will ultimately end in the ring to determine a winner.
