The dvd/bluray releasing mere weeks after the theatre release is amazing for us international fans.
We'd have to wait like a few weeks at most before we get to watch it online in decent quality with subs.
Naruto The Last for example was released on dvd/bluray on July 22nd in Japan (according to the Naruto wiki) and it was uploaded with more than adequate english subs on Kissanime the exact same day.
I wonder if DA2 will completely be ignored and not be mentioned, since I expect Kari and TK to have their old Digivice from DW1.The trailer looks very good!!
and it's not a film, it's called ovas.
