Good grieve... They better release these as episodes the day it hits their theaters like Digimon, this amount of wait is insane. And we still have no actual design, trailer, nor cast. Three years were not enough, they need four, so people outside probably won't see part 2 before 2022....
On the bright side we might be getting new artwork in the form of flyers this Friday, according to the site, but who knows whether they will publish it digitally. Very disappointing. I hope they won't release it outside of Japan theatrically - this will really drag the home video release for another year.
