I have high hopes for this line.
There just as cute as the nendoroids, are as posable as figmas, and are at a very sweet price line.
I honestley don't see it competing with nendoroids though.
The whole concept of the Nendoroid is that; It's your favorite characters as chibi's!
The vibe I get from Cu-poche is more like; Your favorite character, as a cutesey kid!
You might go and think; that's the same thing, and I would say; no there is a subtle difference between the two.
But as I said, I hope the line does really well, I want to see Mami and Kyoko come out from for this line. (Mami is already in the works. :D) As well as ALL the girls from the idolm@ster line; not just the "top" ones.
My two cents... (sorry for the long post.
