There is no indication that it is a WWE vignette, or another company, however one thing is for sure. Jon Moxley will be returning to a ring; somewhere. The Dean Ambrose character was a watered-down version of the Moxley persona that was made popular in various independent wrestling companies, such as CZW, prior to the debut of Dean Ambrose in the WWE.
Arguments for both sides could be made that it’s a WWE video due to the quality of the video production, however we don’t have enough information on vignettes for the upstart company, All Elite Wrestling (AEW) to determine that it’s not a video they produced either.
