So, the 930 Yen were a Kumi-thank-you-price and they mention the best live selection by fans and staff was done by questionnaire (tho not which one) and them showing footage from those lives.

She said she wants to continue to sing for 10-20 years.
Throughout the whole 20th anniversary year they're going to upload more than 150 full scaled PVs on her youtube account, according to their release date (yesterday all songs released on December 6 were uploaded).

He did make a mistake with the setlist tho - she didn't perform Fake Tongue, that was only in video.
