Cena to donate brain, WWE headed to Hawaii, top NXT names to work in Japan, Interview with Styles, Mulligan passes away, WWE faces class-action lawsuit over Network, Nakamura's theme makes waves, Brie's new WWE role, and Questions on the marathon Mania, talents using agents, using AJ to help get Reigns over, WWE's monitors, and the Gorilla position

John Cena plans to donate his brain to science after he passes away. That's great news for future research purposes.

WWE has announced a show in Hawaii on June 29, leading into their July 1 and 2 shows in Tokyo. Chris Jericho, Shinsuke Nakamura, and Asuka are all listed as being on that loop, so it's safe to say they'll be part of WWE's return to Japan. I wouldn't assume that means Nakamura and/or Asuka will be "called up" by then, but it does look like Jericho will be staying around longer than initially expected.

AJ Styles talked about his jump to WWE, working with Vince, and more. Some are speculating Karl Anderson and Doc Gallows will debut in some fashion during Styles vs. Reigns at Payback.

Everything else from yesterday is after the break.

WWE announced more records broken by Wrestlemania 32. Those are all great milestones for them to reach. The WWE and Wrestlemania brands are still very strong.

WWE Hall of Famer Blackjack Mulligan has passed away at the age of 73, following a lengthy battle with poor health. PWInsider covered his career, which included some really wild moments. He sounds like a really kind man. He'll be missed, and his legacy will live on.

- Highspots.com has released a tribute video for Mulligan.

WWE is facing a class-action lawsuit from former performers seeking royalties from WWE Network. That could have big implications for WWE and its emerging technologies.

Shinsuke Nakamura's WWE entrance music is the No. 1 song on iTunes' soundtrack chart. That's a really good sign of fan interest in him. I hope he has a bright future in WWE.

Brie Bella has transitioned into being an ambassador for WWE, acknowledging the end of her in-ring career.

For my take on yesterday's PWInsider.com questions:
1. I think the show was great and we got a lot of bang for our back, but I also wish they would have given us more of an inkling it was going to be a long night.

2. It's probably easier and more straightforward to negotiate with the talents themselves. I would think agents might get their clients a better deal, though.

3. Using wrestlers who are good workers to help less-experienced performers goes back WAY before Cena. It's gone full circle to where now Cena is one of their most solid workers and is used to get other people more "main event" ready. I think it's a great idea to have the well-traveled former IWGP Champion help Reigns improve. Hell, AJ was in a similar position in TNA when he had to prove he belonged as a main eventer against the likes of Kurt Angle, Sting, and Booker T.

4. CRTs probably look more impressive as weapons anyway. Plus, for what little WWE uses them for, they don't need more expensive TVs.

5. I really wonder what that dynamic was like, considering Vince called the shots on how commentary should be.

More wrestling tomorrow.
