They will also be releasing a concert DVD of their oneman concert at Shinagawa Stella Ball back in October and it will come out the same day as the single.
I am a bit disappointed that the single is not like the previous releases and does not have bonus tracks for two of the versions though. I loved Bling Bling Princess' iya iya iya from Bombastic and in general I am a sucker for bonus tracks. But I am still happy to know that there will be some new music from the group I can enjoy in the near future. And hopefully as a double A-side that puts us that much closer to the group's first full album.
In any case this release comes at a perfect time as I have yet to pre-order a copy of Michishige Sayumi's graduation concert BD and since these share a release date with it they will be a perfect addition to that order for me. And since the only difference with the single types is the cover art then I have no issue with only getting one of them and save some money.
