According to Pwinsider.com, WWE has begun to send out invites to media representatives for an event in Las Vegas at the Wynn Hotel during the International Consumer and Electronics Trade Show on January 8th, 2014. These invites also reportedly note that WWE Chairman Vince McMahon will be on hand for this special announcement. Now what this announcement will actually be about is not clear.
Pro Wrestling Examiner suspects this announcement could involve the roll out of the WWE Network, a subscription channel that WWE has been laboring over for years. The Network is detailed in this Top 5 article here, and it could drastically change the future of WWE in many ways.
WWE could also make an announcement about the 2015 Wrestlemania. Around this time last year, the company announced that New Orleans would host it's Super Bowl of sports entertainment in 2014. It would be reasonable to assume WWE could use this fit setting of a corporate trade show with a tons of media on hand to announce where they are bringing their biggest annual event in the next year.
