Vince McMahon and WWE changing their minds on WrestleMania 31 main event?

Speculation and fantasy booking has been rampant since the Philadelphia crowd and the Twitter-verse erupted following Roman Reigns' Royal Rumble win.  That victory would usually mean that The Big Dog was headed to a WrestleMania showdown with WWE World Heavyweight Champion Brock Lesnar.  Reigns and WWE's reaction indicated that that was they planned it to mean.

Since shortly after Royal Rumble, however, Vince McMahon and company have been couching their bets.  As soon as they were out of the snowstorm and back in front of a live crowd, they've been charting a course that could put Daniel Bryan back in the Mania main event for the second straight year.

Over the weekend, WWE.com tested the temperature of the online WWE Universe with a poll asking which of the men now scheduled to face off at Fast Lane for a shot at Lesnar is "more deserving".

And it wasn't close...

Now, Dave Meltzer over at The Wrestling Observer (subscription required, but recommended) is saying that McMahon has decided to pull the trigger on a change for March 29th show in Santa Clara, California.

But he's not pulling Roman out.  Instead, after processing the fan response and meeting with his team, Vince has reportedly decided to return to the Triple Threat well for the second straight year.  So rather than Brock Lesnar vs. Roman Reigns for the WWE title and Daniel Bryan vs. either Sheamus or Dolph Ziggler, the WrestleMania 31 main event will be - again, according to Dave Meltzer -

Brock Lesnar vs. Roman Reigns vs. Daniel Bryan

Do you put much credence in this report, Cagesiders?  Is this really what the fans want, or is the WWE.com just the latest example of how different "Smarks" are from the house show crowds who love Reigns?

Is part of the reason for the change to ensure that the Rumble winner doesn't have to work a long match without a general to call the action, as Steve Austin worried?

Does the possible switch change the outcome, or just give Roman another big name to go over as he's crowned?

This is the kind of rumor that spawns even more questions than it answers.  And whether it ends up being true or not, that's probably the best thing for WWE's business.
