As a business decision, it's smart. If the brands will truly be separate, they would need their own special events/PPVs. If they don't have their own events, what would be the point of having undercards? They wouldn't be featured on these events at all. So it really helps on getting those talents noticed and those talents getting chances. Different talents, different stories, different creative teams, etc... will warrant needing their own events. It adds more value to the Network. I'd gladly watch more than one PPV per month with my subscription. It also lets WWE have another PPV gate per month with higher ticket prices and draw a few more bigger gates per year. It's smart on their end.
My only question is MitB as a PPV. What brand would that be exclusive to? Or do you rename the PPV and stagger the MitB matches maybe six months apart to sort of rotate the briefcases? Or do you trash the event as a PPV all together and have two MitB matches at Mania? I would have a hard time believe they would trash the PPV all together seeing as it's actually more entertaining the last five years than any Survivor Series in recent memory.
I won't mind it. Gives me something to do on a Sunday night.
Hopefully they keep the one world title. Then you have a MITB match, whether it's Wrestlemania or Summerslam with both brands involved. The MITB winner can then appear whenever to cash in if they so choose.
