>>74182985The 3D debut is a special event, and you need to schedule at the best time, because it is more than a simple stream, is essentially a second debut, that can attract a lot of outsiders who just want to see the special event. For EN you also take into account stuff like VISA, their schedule and the sudio's schedule, because Cover didn't build that 3D schedule just for Hololive, but also as a way to diversify their business. They are renting it to others too - other vtuber agencies, game companies, etc. Anyone who needs a motion 3D studio. So it wouldn't make sense to make Advent fly to Japan only to record their 3D debut. Instead they will record it, when they go to Japan for more things. There are a bunch of events in the summer that will likely require for them to go to Japan, and that is the obvious perfect time for their 3D too.
