^ Berryz owns them all
There is no way UFA is going to make one group look bad on purpose anyway. Of course you can like both groups too but some people don't like them equal just like they don't like all members equally. I think that's normal, even for non H!P groups, perhaps just a bit more extreme because H!P is mostly about Idols, Idol-Pop and that implies that a lot of people
worship some members more than others since they are even treated different by UFA (PBs, line distributions).
I am looking forward to this even though I agree with Anton about them better having their own concerts. But I remember saying that I would find a joint concert interesting some year(s) ago, and yeah, for once it's interesting too see how that works and all, to see just both kids group without MM.
But now that I am liking one group much more than the other it's also not so great because it replaces a spring tour (for both? C-ute had so many tours lately I didn't follow them anymore, but Berryz is not having one this year for sure). So people who are less interested in c-ute have to watch them too while seeing less Berryz perfs because of them. Vice versa.
Long story short, if I had to chose between a spring tour (e.g. 1hr concert) with Berryz and C-ute both 30min
or Berryz alone 1hr I would probably chose the Berryz only version... (or both having a tour alone with 1hr, even better).
Too bad the DVD is most likely not going to be release before summer. Still so much time to wait.
