You just beat me posting about it!^^

It's not the first FC video with her dancers, we already had one here or there in the past.
If you think about it, she already had songs that didn't make albums in the past and then were used later (like Sweetest Taboo from WOML later for AND or on singles Good☆day).
I actually think that's just the way she works - recording all the songs she feels recording for on album cycle and then choose at the end.

She also confirmed in this video, that she wants to remake both arena tours Black Cherry and JAPONESQUE for halls in a way you can only experience it in a hall.

And update from the last days: She's still rehearsing every day and after coming back from Vietnam she got really sick and couldn't attend rehearsals for one full day.
