Following the departure of Kenny Omega from New Japan Pro-Wrestling last month it lead many fans to speculate if the former IWGP champion could remain with NJPW work with both promotions. However, within days of his title loss it was officially announced that New Japan would be sticking with Ring of Honor instead of joining forces with All Elite Wrestling. This isn't really surprising albeit a little disappointing, but I guess it's just a part of the bigger picture that has been coming together since the announcement of this brand new promotion.
One thing comes up from there is does this mean that AEW will not be working with CMLL down in Mexico either since that promotion has had a decades long working agreement with CMLL. However, with the signing of former AAA World Cruiserweight Champion and would hold the title until losing the championship to Laredo Kid on February 16, 2019. Though this could mean nothing but it could also set up a working agreement with the two fledgling wrestling promotions providing some stability for both companies. Now All Elite Wrestling has set up some sort of agreement with OWE or Oriental Wrestling Entertainment as members from the roster are a part of the company. It is unknown if there is an agreement in place or not but we do know that the Good Heart stable and Cima are among the names from OWE set to appear for AEW.
Overall though if the last few years have proven anything it's that both the companies and talent can benefit tremendously from working agreements it doesn't matter if it's ROH & NJPW or Evolve and WWE each company has been benefited in a variety of ways from there respective agreements and I think it's only a matter of time before AEW makes some of their own.
