On the other hand, ID have much better concentration but might be lacking in people buying digitally.
End of the day hololive is a business that want profit and they view sololive as "must gain big profit" since they comes with extra cost like hiring the stadium, staffs, etc.
They started feeling out kaigai events like dreamhack to gauge viewer interest. It'd take maybe 3-5 years of feeling shit out until hololive give the green light to an EN sololive. Unless dimitri can convince upper management otherwise. Or one of the talents (not named mori) sold out their concert as a pl so they prove they have what it takes. Until then holo will look at album sales, because it's a good representative of people who would spend money on extra stuff like the concerts.
I saw people bemoaning that they wont make the drive/flyin from east coast to west coast for the current events on reddit all the time and someone at cover probs reading them too.
