The main Digimon website updated this weekend with some new information about the characters and story.
From the story portion:
Digimon Adventure tri. Chapter 1, “Reunion”
It’s been 6 years since Yagami Taichi and the Chosen Children went to the other world, the Digital World, in that summer adventure, and 3 years since Yagami Hikari and the others’ last battle against BelialVamdemon (MaloMyotismon for my fellow dub nerds).
As peaceful days continue, the gate to the Digital World closes at one point. Time passes without even the Chosen Children knowing why it has closed… (what the fuuuuuuuuuck)
Then, one day, a Kuwagamon suddenly appears in Odaiba. The town is destroyed and people flee in panic from its rampage. Taichi, who happens to see the Kuwagamon by chance, chases after it alone in order to stop it. But Taichi is powerless to do anything against the Kuwagamon by himself.
“It’s no good… I can’t do anything on my own…”
As Kuwagamon closes in on Taichi with a roar, his Digivice suddenly begins to glow bright–
“Taichi, you sure got big!”
At the sound of that familiar voice, the story turns largely once again.
Yagami Taichi, 17-years-old, high school.
The adventure evolves once again…

so in a shocking turn of events, 02 is still canon and somehow the writers are going to make this work into the established canon. this makes me actually okay with the fact that the 02 kids are looking to not feature prominently because their epilogue ending was even bigger bullshit than yamato's ending so yeah, spare my children. on the flip side, i hope we get lots of QUEEN MIMI ♥
