>>4089650HoloEn2, gen 6, and Vsingers will be around 80k-110k each. Vsingers has the higher potential ceiling if their opener is crazy talented, and raises the expectations for the rest. Gen 6 might have a higher floor just because it's been awhile since an all JP gen was debuted.
NijiEN 2 will completely depend on how gen 1 performs. They need to grow their fanbase so the next gen actually has legit hype going for them when they debut. It's the reason why it drives me crazy when they keep self sabotaging themselves sometimes.
HoloID is irrelevant except for Moona. She's the only one I expect to break 50k on her 3d debut.
HoloEn 3D is where it's at though. I'm thinking 100k-150k between Ame, Ina and Mori. Kiara probably gets lower than that. 80k would be the lowest I'm willing to bet. Gura probably breaks 200k easy with her 3D. The real question is does she get close to 250k-300k.
