Finally we have not only a release date for Kis-My-Ft2's debut single but also the title track. It looks like the A-side will be Everybody Go, which the group has already performed on Shounen Club last month, and it will be released on August 10th.

The greatest competition they have for the weekly number one will be the AKB48 subunit, DiVA. But I think with the drama tie-in and having a long established fanbase will help give Kisumai the advantage. And of course we still don't know how many versions the single will come in or if there will be any special campaigns to help boost sales tied to it.
Though I will admit I feel a bit disappointed with the A-side. I wasn't impressed with the song on SC but I find I usually enjoy the B-sides for singles when I don't care for the A-sides when it comes to most Johnny's.
EDIT: The information seems to be all over the place for this release. But it has been confirmed that there will be three editions of the single with the two LEs having different DVD contents, one of the PV and making with the other being live footage from their last concert. The RE will have a bonus track for four tracks in total.

EDIT 2: Just when I think I've found most of the information I find more. Avex Trax has their official website for Kis-My-Ft2 and has a countdown for the release date. There are also special member versions of the single (7 versions in total) that will be released through Japanese online store mu-mo. These version only have two tracks but come with a message from each member as well as an 8-page booklet and roller skate key holder for each member.
