The network doesn't give a shit, you know why...?
Vince McMahon can and WILL compensate the monetary loss the network receives during those two hours, so they don't lose anything anyways, and Vince gets to produce a product without commercials to appeal to the fans who complain about breaks in the middle of long exciting matches, and to also boost promo-work (think about the amount of time spent between matches during commercials where the ring crew is adjusting the ropes, etc. It'll give them the opportunity to run more backstage work (Triple H vs. Orton) leading up to the Pay Per View.
It might actually be successful.
