You don't need Netlfix just for one show. I had an outage the night Ripley returned. Used my phone data, went to YouTube, and the clip was up at 11:01pm. Felt like I had missed nothing.
The WWE/Netflix relationship will likely continue though and I think we'll eventually have the Network and PLE's there. Plus future docs and limited series might be produced by Netflix. I can easily see a 5 or 6 episode Road to WrestleMania series happening in a few years, covering the ins and outs from the Rumble to Mania.
