Official artist and label websites just confirmed NICO's upcoming new song. As playasia.com had listed earlier, the title of this new song is "Natsu no Daisankakkei (夏の大三角形)." It will be the latest CM song for Calpis Water, which is scheduled for nationwide broadcast starting March 20 (Tuesday).The following day, March 21 (Wednesday), the song will be available for digital download (Chaku-Uta) at http://recochoku.com/rs/nico/.
It features the boys' comments as well as preview of the song and CM (maybe the PV too?).

No mention of a CD release just yet. I'm pinning on them announcing it during their Chiba live, which is conveniently scheduled on March 20 too.
