Last year was big for World Wrestling Entertainment (WWE), but if you think you've seen it all, prepare for awesome as the leader in global sports-entertainment brings in four new Japanese pro wrestling stars.

Yes, reports are flying that Shinsuke Nakamura, AJ Styles, Doc Gallows, and Karl Anderson are all jumping from the walls of New Japan Pro Wrestling (NJPW) to star in the WWE scene. Rumor has it that the four have given a notice of their plans, but it seems like they still have things to settle, reports Christian Post.

Nakamura is expected to stay for a while, although it's pretty obvious that he will be vacating the International Wrestling Grand Prix (IWGP) intercontinental title -- just like Alberto Del Rio .

Anderson, Nakamura, and Gallows are booked in February for the Ring of Honor  in  Las Vegas -- so March is the earliest date for them to be in WWE.

Nonetheless, fans are rooting for their surprise appearance at the 2016 Royal Rumble where Roman Reigns will defend his WWE Championship, reports What Culture.

Styles will most likely appear since he is not contracted with the NJPW and the Ring of Honor.

As the four crossover to WWE viewers are excited to the energy that they will bring in. Fans are especially eager to know if the Bullet Club will be together again.
