If you're a die-hard wrestling fan, you'll be happy about this news.
The official WWE Network application is now available on the PlayStation 4, PlayStation 3 and Xbox 360. It isn't ready yet for the Xbox One; the app will hit Microsoft's new console some time this summer. There was no mention of this app showing up on any Nintendo devices.
In the US, WWE Network users can check out live shows and archived content for only $10 per month (provided you commit for at least 6 months). This subscription gives you access to all 12 WWE live pay-per-view events such as "Wrestlemania 30," along with new reality shows and documentaries. …how do you make a documentary about something that's 100% fake? Oh, just kidding; I get the concept.
Anyway, the WWE Network app is also available on PCs and mobile devices. The image you see here is how it will appear on the PS3 and PS4. As for why it's taking longer to reach the Xbox One, we don't know… I'm sure it's some bizarre legal snafu, though.
