It just been announced over on the offical twitter account for the Digimon Adventure 20th that more guests have now been announced for the upcoming Digifes which are a couple of voice actors from 02 which will be joining the DigiFes 2019.
Junko Noda who voices V-Mon will be attending this event along with the Naozumi Takahashi who voices Wormmon.
It has also been teased that there will be some sort of video at this event which I gather will be a trailer for the upcoming movie but hopefully more info will come in the weeks leading up to the event.
I will do my best to keep up to date now with the latest Digimon news now that I have a bit of free time on my hands.
