"Ad Age has named Stephanie McMahon on their "40 under 40" list for 2013. They mention her current role in WWE as "overseeing the development of TV, pay-per-view, print, digital and social-media programming" adding her influence will grow if the WWE Network ever launches. As for why the Brand Extension ended she said, "We are all telling the same stories. And digital and social offer the ability to continue storylines 24/7 so our fans can consume the content anytime, anywhere on the device they prefer."
I'm fine with a brand split being over only in the case that they get rid of the WHC and US title. It'll bring back prestige to the WWE and IC titles.
