The only remotely possible way I see something like this happens is if another turf war breaks out between WWE and some other promotion and that's not likely to happen. For that to happen, a promotion would have to have access to immense financial resources, either via its owner or through investors who trust the people in charge of running the promotion to run the promotion as they see fit, and a real TV deal for a real show on a real network. What I mean by a "real" sort of deal is that it'll have to be a show that's episodic and new each week like Raw or SmackDown, not taped weeks or even months in advance and/or shown through a syndication TV deal, that airs on prime time television on a network that gets lots of viewers in the first place. ROH is syndicated and its current crop of episodes were taped 5 or 6 weeks ago, Impact is sometimes taped months in advance and is on a piddly network that they're parting ways with sometime next year, and New Japan is on AXS TV, has been for years, and is really nothing more than a clip show in which matches that've taken place often months in advance on big shows like Wrestle Kingdom or select matches that're part of the 10,000 tournaments New Japan has each year are cherry picked to air. As far as a network goes, one of the broadcast networks like NBC, ABC or CBS, even the CW, are examples but are highly unlikely. As far as cable networks go, networks like Freeform, WGN, AMC, MTV, even HBO or Showtime are possible; Freeform is owned by Disney so a family friendly product will be required, WGN has been around for a long time and isn't exactly a powerhouse but it could provide a place for a company to grow and increase its worth, AMC, HBO and Showtime are all critical darlings now who might consider pro wrestling to be too low brow, MTV could certainly use something besides showing marathons of Ridiculousness episodes and Jersey Shore spinoffs. Streaming services like Hulu, Amazon and Netflix are also possible but that's a crapshoot. I'm also fairly sure that networks like Syfy or FX are out of the running as I have little doubt that WWE would insist, through the new contracts t signed with Fox and NBC Universal earlier this year, that no other wrestling content, unless it's WWE produced of course, can run on any networks under the Fox and NBC Universal umbrellas.
There are rumors that Cody, the Young Bucks, Adam Page, Kenny Omega, Jim Ross and Chris Jericho are forming a wrestling promotion and that the co-owner of the Jacksonville Jaguars is a financial backer. Allegedly, they filed for a bunch of different trademarks, most of which contain "Elite" as part of the name of the promotion and that mail, phone calls or both regarding the promotion have been delivered to the Jaguars stadium. Said co-owner is Tony Khan, he's 36 years old, and his father is Shahd Khan, the other owner of the Jaguars. Khan, Sr. was ranked #70 in this year's Forbes 400 and has a net worth of about $7.4 billion. Now IF all of this is true, then this new company having access to that sort of financial backing is a big deal for them but, again, if it's true, they're still in the very, very early stages of anything and unless contracts and legal papers have already been drawn up and signed, it could easily fall apart at any given time; as a result, it's way too soon to read into or expect much out of this at this time.
