I...
I like Okada.
I like Okada a lot.
I know the match vs Tana will be good and hope that the future holds a feud with him and Naito. Tana can then go and beat up some young boys for a year or something.
I like Okada too. Sick dropkick, Rainmaker, while simple, is an awesome finish, and although Gedo is most of his act, he comes across as an effective heel and a pretty cool baby face.
Honestly, there's really not an NJPW wrestler I actively dislike, except for Yujiro. And Fale. And Gallows. And Rocky Romero. But yeah, that's pretty much it.
I could see Tanahashi feuding with Styles (presuming he sticks around post-WK) for the IC title, or going after the tag belts with #BIGMIKE. Not sure who'll they are going to set up for Okada, but I don't think it'll be Naito right away - seems Ingobernables/Meiyu Tag will run for a while longer. Nakamura's an option but, again, I don't think it's something they'll do right away.
Which is why I'm going with Goto beating Naito at WK and then winning the IWGP title at New Beginning, (Goto is still owed a shot for beating Okada in the G1) then losing it to New Japan Cup winner Naito at Invasion Attack. This finally gives Goto a reign (a two-month transitional reign but a reign nonetheless), freshens up the main event scene, and creates a hot new feud in Okada vs. Naito. You can throw Nakamura in there too, as hopefully he will have dropped the IC belt by this point (to AJ or otherwise) since he's also owed an IWGP shot for beating Okada. While I'd love to see AJ win the IC title, I get the feeling he wants to wind his career down and spending half of the year in Japan away from his family isn't ideal anymore.
