According to a report on Wrestlezone, there might be a title switch at the WWE's live event in Tokyo on July 4th, which will be shown exclusively on the WWE Network. WZ claims that Kevin Owens will be dropping his NXT Championship to Finn Balor, so that he can move on and take the United States belt from John Cena at an upcoming PPV.
If this happens to be true, it would make a ton of sense. KO needs to inevitably drop his title and Finn Balor seems a logical recipient. On top of that, Cena will need to move back to the main event picture at one point and Owens seems like the best person to take his belt.
