OG recording????

People talk about this @2ch...
And quoted men0 from Jpopmusic:
All the H!P OGs have been recording something together this week. It's mentioned on some of the blogs and Maeda Yuki has said something on a radio show, but what it is exactly is a big secret. It doesn't look like another TV show or something, more they have been recording a new song.

Yaguchi, Mai, Yuko and Erika wrote about the secret recording on their blogs.

Can't wait to see what is this!!!!
It's gonna be something awesome, I know it!!!

Althought, everytime the OG is featured, Yossi is pushed to the back...

I wish it will be a single (or album) followed by concert xD
