It could just be a mistake, but based on the banner tweeted by MegaHouse, it seems like the Digimon Collection (DigiColle) Data 3 is already on the works.
Assuming the rough translation and the Romanji texts on the banner, the next set of trading figures following Data 1 and 2 might be scheduled for a March 2016 release while pre-orders might open this November.
Following the previous DigiColle releases and the announcement of Ken under the G.E.M. series, Data 3 might feature the Adventure 02 Digimon partners, except Patamon and Tailmon and their In-Training and Babies forms which were previously on the first Data sets. This left us with Rookies V-mon, Hawkmon, Armadimon and Wormmon and their Babies and In-Training forms Demiveemon and Chibomon, Pururumon and Poromon, Tsubumon and Upamon, and Leafmon and Minomon.
As mentioned, we can just be assuming here
(why can’t I read Japanese?!?) but as usual, we will follow up if there are any progress so stay tuned for more updates!
