if the speculations are correct, according to the video
we will see a new trailer, having a vague image of Kanji on
http://www.mayonaka-tv.jp/
either today, tomorrow or at May 14
then we can be sure that the site is following the game's calendar
EDIT:
checked the site
countdown timer shows it's a day after today
so it'll be may 13 by then
but it's at midnight, so it'll be may 14
can we conclude that they're following the game's calendar now?
