It was announced at the May 4th concert for Hey! Say! JUMP that they will finally be releasing their first album sometime this summer. No more information about the album was announced at the time.

It's my personal opinion that we'll be seeing either a late June or an early July release of the album, so that way they can use the Summary concerts that being in mid-July as a way to promote the release. And hopefully this means we'll see the album information up on Johnny's net soon as by now they should be announcing June releases, though they did have us wait a few weeks after Hitomi no Screen was announced before they put up information for that single.
But whatever it may be I'm just so happy that HSJ are finally getting their debut album, especially since it's taken them over 2 1/2 years since they debuted to have this.
