AAA announced it several weeks ago. They would be doing a tournament involving trios from multiple promotions and parts of the world. ROH was rumored to be in on it due to their work with Alberto Del Rio. NOAH already has a relationship with AAA. And now the official date and location have been set and the unexpected here is the fact that both TNA and ROH are in it. More companies may be added, but that's a heck of a grab. Some of Lucha Underground's non-AAA talent may also be added as the independent U.S. team. Right now no rules are set on this event. Or if it will be available on iPPV for viewers outside Mexico.
