They won't though. They'll fill it with retarded reality shows and those amazing original movies they green-light. And no one will pay for that. The only way to get people to pay for that shit would be to have Raw or Smackdown on the Network.
I hate reality TV but poorly done reality TV is even worse, and the WWE Network will be full of it.
Don't get your hopes up.
