This Week in WWE debuts at 2:30pm today on the WWE Network. It’s basically a recap show of everything from the past week. There is a show called WWE This Week that airs in Europe so it could be an updated version of that show.
WWE will slowly be adding more older content to their WWE Network archive. They will be adding old WCW Saturday Night episodes, Clash of the Champions, and more Raw episodes over the next few weeks. The company did not want to give too much away on the free trial and they want to rollout some stuff on the live feed first before adding it to the on demand archive.
As noted, if the Xbox issues are not already fixed then the company expects to have them fixed by Monday.
Roku users should be able to watch without issues if they get the latest WWE app update.
