The "WWE World Heavyweight Championship" as it will now be called will be the WWE Title. The World Heavyweight Title will be retired. There will not be any new title made for the new championship, especially given the WWE Title belt was only released less than a year ago.
The E! Network also announced last night that "Total Divas" will return in March 2014. The popular first season of Total Divas as you may know was a ratings hit and will return rather nicely in time for Wrestlemania. No doubt you will see Total Divas in some capacity at Wrestlemania.
