New Hey! Say! JUMP release… maybe?

So I got a really bizarre email from HMV today advertising the theme song for Yamada's Ansatsu Kyoushitsu movie, and found a longer description on the Tower Records website here. Apparently, a "mysterious" 9-person unit is going to provide the theme song. The whole this is really odd and confusing, and knowing Johnny's, I'm trying not to get my hopes up that it's JUMP, but I supposed we'll just have to wait and see.

Here's the text from the article in full, as translated by me.

Mysterious 9-member unit will provide the theme song for Yamada Ryosuke's starring movie, "Ansatsu Kyoushitsu"

"Koro-sensations" will be the theme song of Yamada Ryosuke (Hey! Say! JUMP)'s starring movie, "Ansatsu Kyoushitsu, which opens on March 21st, 2015. The nine members, who were sent to assassinate Koro-sensei, failed their mission and were "punished." So, in order to promote the movie and make it a big hit, as produced by Koro-sensei, they were turned into a unit called "Sensations" and made to provide the theme song… For the highly-anticipated live action movie adaption of the hugely popular comic currently running in "Weekly Shounen Jump" that's been a big topic this spring, "Sensations" will give their strongest support with a hyper-pop turn overflowing with a sensation of hurtling through heavy metal guitar sound and digital sound.The limited first press DVD will have the "Koro-sensations" video clip "Battle Mode" and the making-of footage "Active Side." The CD that comes with it will have "Koro-sensations" and the original karaoke track. On the regular edition DVD, in addition to the "Koro-sensations" video clip "Battle Mode," also included will be the "Koro-sensations" video clip "Operation Mode" and the making-of footage "Passive Side."
※ The jacket image will vary between the first press edition and the regular edition.

More information can be found on the J-storm website and on the "Special" releases page on Johnny's Net. The fact that it's J-storm makes my hopes get up further, but I'm trying not to jump to any conclusions.

As always, I'm happy to answer any questions, but I'm getting surgery tomorrow, and unfortunately, I'll be away from my computer for a little while, so please be patient with me! Let's hope this is good news for JUMP!
