It has been announced that NEWS will be doing the opening theme song for the upcoming anime series Kindaichi Shounen no Jikenbo R that will begin airing October 3rd. The title of the song will be Yon Juushi and there is no word if it will be released as a single.
Johnny's net announcement (English)
If NEWS keeps the pattern they seem to be moving into there should be a new single around the end of the year or start of the new one. I can see this song perhaps being a double A-side with a newer song for that, or even being held off on a CD release until the next album comes out. I really hope it will be the former than the latter though with no more information even all that is just speculation.
And of course this is not the only new song from the group that it is unknown when it will be released on CD as the group also has the song Sirius, which is being used in a commercial for bras currently. If anything it at least gives hope that it will not be too long a wait for another CD release from the group.
