The announcement, which came after Omega defeated Jon Moxley for the AEW World title, also confirmed that both companies had entered into a working relationship, and Dave Meltzer of the Wrestling Observer Radio has provided further details.
According to Meltzer, by way of Ringside News, the plan had been in the works long before last night's Dynamite. It is believed that Callis pitched the idea to Tony Khan, and the AEW president went with it.
The journalist also stated that the partnership will see both companies exchange talent. According to the pundit, it's the ideal way for Impact Wrestling's stars to become familiar in the eyes of the AEW faithful, as some of them will be regulars on the company's programming someday.
"It does open up the doors for people which is great for Impact because some of their guys are going to end up on AEW television probably."
Callis has also featured on AEW programming on more than one occasion. He provided some guest commentary at the promotion's last pay-per-view, Full Gear, suggesting that both parties were open to collaborating in some capacity.
