That's how I think MM sells better than other acts, coz there are more members.
I wonder how big the fanbase of Berryz' 4 front girls is. Bigger than Miyo/Yui that's for sure. I've seen some sales numbers of the tour goods from W/Berryz tour last year, and Momo's, Miyabi's, Risako's sales were almost as good as Nono's and Aibon's. And I don't mean 3 of them combined, but as individuals. It seems like their fanbase is getting bigger and bigger.
With vi-yu-den, we all know it's 99% Rika fans. And some fans haven't even opened up to vi-yu-den, yet... Too bad.
ETA: From last night's DOKYU.

I haven't watched this ep, yet. But I guess, Miyo probably just said the show's title and nothing else.
