WWE Champion AJ Styles, United States Champion Shinsuke Nakamura, Luke Gallows and Karl Anderson's contracts will expire in early 2019, according to Dave Meltzer on Wrestling Observer Radio.
Meltzer noted that New Japan Pro Wrestling has "absolute interest" in bringing back “The King Of Strong Style” to the company. There’s no word on whether the talent is looking to leave or stay, but WWE will most likely offer a big contract to each man just to keep them away from NJPW.
Styles has talked about retiring soon, though he’s never given a timeline or date. Or course, we’ll keep tabs on this story when an update is available.
