Rosalina is the only one I care about and just from the pic she only looks ok, but I'll need some better pics to make a final judgement. Lately Nintendo has been more spot on with the official amiibo pictures as they've updated the ones on their website to reflect the final product and not the the prototypes so I think these will look quite similar to the way they do here. I think they're learning from their mistakes. It looks like they've finally learned their lesson about colored supports too.

As mentioned the amiibo website has been updated and includes the new retail models for the first wave. Taken in good light they don't look all too bad so idk
I still need to see them for myself before I decide whether or not I'll buy any. I have a feeling their going to look and feel cheap and that I could probably spend a little bit more for some better looking figures...
If they're nice looking though, I'll definitely get Kirby, Sheik, Toon Link and Yoshi. I doubt I'll use them for their 'actual purpose', they're just some of my favorite Nintendo characters and I would like to have the figures if they look nice.
