4. Indie wrestling, ROH, NJPW and NXT will probably lose momentum
With AEW trying to position itself as the new big man in the room, it's not hard to see how everyone else other than maybe main roster WWE will suffer as a result. Why watch or support indie wrestling like PWG when AEW will likely do the same thing with much stronger production values? Why watch Japanese wrestling when the AEW will likely do the same thing but without the language and cultural barriers? Likewise, why watch NXT when you could fight the machine and support the shiny new toy that isn't owned by Vince McMahon?
By potentially taking away attention from other promotions, All Elite Wrestling could unintentionally fragment the industry rather than expand it. There are a finite number of fans and hours in the day to watch, and since it's unclear if anyone has a plan to create new viewers from scratch, one can only assume that a Double or Nothing ticket buyer might skip out on the upcoming New Japan G1 show in Texas. Talent raids could also spell disaster for rival promotions and though ROH and NJPW have survived them before, AEW having a highly advantageous $100 million budget at their disposal could spell the end of the former two companies expansions.
