As long as their songs are Tanpopostyle and Pucchimonistyle, I'm DOWN WITH THIS!!
There are so many units in H!P right now that don't have a DEFINITIVE style. C-ute, Berryz and Momusu all have both cute and cool songs; if you only heard the instrumentals of singles before the release, it'd be impossible to guess which unit is going to get the song.
But when you listen to old Tanpopo or Minimoni, you can tell instantly what it is (whether Tanpopo 1st gen or 2nd gen, even if they were different from each other, Tanpopo 1st gen had a definitive style and 2nd had its own). Pucchimoni's songs maybe didn't stand out that much as a cohesive style (to me all their singles are very different from each other), but their spirit on stage did.
So good stuff that could result from this:
+ Groups that have their own unique style and sound and not one that changes for each release
+ Lots of interesting, fresh mixes of people in units (Eggs please)
I'd love to see Sengoku in Tanpopo if Tanpopo still has adorable love song stuff. Because her smile could really melt an iceberg. :3
Bad stuff that could result from this:
+ If the songs are crap, they might tarnish the image of the golden old groups, as well.
+ If they shuffle the members, I'll be mad. New units need more time to find their place today. There was already backlash during 5th gen addition, today shuffling would suck even more because hardly anyone outside wota knows who these girls are.
Just have to trust that the management has put a lot of thought into this!!
