No, I meant like a confirmation of the title and/or release date.

Not the actual performance or radio previews.
For any other H!P group, it feels like 2-3 months before. (The release date of Berryz' previous single was officially released by UF in March, while both S/mileage's title and release date was at the end of June.)
With Morning Musume, they want to hype it up, so they have recently had the habit of release any type of detail nearly or at a month before. The only confirmation we had was from 1 store who put up a sign one day and a reliable Taiwanese website.
