What I'll be curious is will AEW have relationships with NJPW, ROH and Impact. Will there be a network of indy/second tier promotions sharing talent. A lot of guys have established relationships with certain promotions but will it be a quasi-territory thing with belts going between the promotions and continue to do joint shows like ROH and New Japan do. All-In and the Jericho Cruise were just joint venture shows. If they build a strong network of those promotions, I think the can be the best alternative/opposition to the WWE machine.
As much as I like the guys in the Elite, I don't know if I'd watch a promotion of just them. Kenny still being IWGP champ and being a part of AEW would be fine with me.
AEW seems to have A TON of money behind it. Khan is worth over double what Vince is.
So, they are going to be able to secure a lot of top talent, and I doubt, just like WWE, they will want those investments to possibly be injured working elsewhere.
I think AEW will continue to do joint shows, All In could be pretty awesome if AEW, NJPW, ROH etc all go in and bring their top talent (Almost like if WWE did Survivor Series with ROH rather than Raw vs SD) but I'm pretty certain any Wrestlers who sign with AEW will be on exclusive deals.
It seems like January will be the month when we see if AEW is for real, and what it entails. If they have a TV Deal, and speculation is they do, this could be a massive thing for the industry.
