So, em, an interesting announcement at Power Struggle this morning:
Will be Jericho's first match for New Japan since the 1998 G1 tour; and first outside WWE since 1999. Pretty big deal that no one really expected; they'd been working something on Twitter for the last week but everyone thought that was for Jerichos cruise thing, not the Dome. To provide context for non-New Japan people, Wrestle Kingdom is basically their big show of the year, always held from the Tokyo Dome on the 4th January so a pretty big deal, and Omega is very good, and is the leader of the Bullet Club which is a pretty big thing for someone to be (earlier leaders were Prince Devitt/Finn Bálor, Karl Anderson and AJ Styles so pretty well known guys).
For anyone who wants to see how good Omega is there's a whole litany of matches that he's had just this year to recommend; the Omega/Okada trilogy is the obvious thing to recommend checking out.
