The network would feature content from the WWE's incredibly large video library of footage from all over the world, along with original programming. The network may be available through something other than cable or satellite, possibly online only. This would make sense for CES more than a straight TV network would.
ORIGINAL: Shawn Michaels, Steve Austin, John Cena and Triple H will all appear at the January 6, 2014 event at the Encore Theater in Las Vegas, Nevada. Vince McMahon has already been announced for the event, which happens the same week as the 2014 International CES (an international consumer and electronics trade show), which WWE usually has a presence at.
Last year, the company focused on their App, which debuted a few months before CES 2013. It's possible that this event will be the official announcement of the WWE Network.
