>>5212915holoID 3D is finished, but they cannot debut until Covid gets under control in Japan. ID and MaID were all bonked for hyping it up with no definitive date.
holoEN 2 debut was originally supposed to be at the end of July, and were originally going to start being teased in 2 weeks, but Coco's graduation pushed everything back, so people don't accuse them of pushing out a gen to take heat off management for not keeping Coco.
There won't be any future main branch or holoID gens for at least a year, however Cover has definitely noticed the recent upsurge in Korean clips and fans watching streams. There's hesitance to open up a completely new international branch though, with Covid calming down around the world, so holoKR, ES/EU, etcetc are not being considered (for now).
