Kattis' page is really good reference too, although Ryan and fashionista ken seem to be missing. (It's in Swedish but it's mostly just a list of the names so should be pretty easy to navigate anyway):
http://kattisdockor.bloggplatsen.se/201 ... ten-lista/I have a really hard time seeing the similarity with Flavas Liam, but that doesn't mean mattel didn't call him blaine at some point. Ryan and Harley are definitely separate sculpts (if I'm not mistaken, harley was used for Edward Cullen).
Here's ryan and generation girl blaine (the only ones i have atm):

I'd love to see a comparison in profile of generation girl blaine vs cali guy/tango, since some differences are easier to spot from that angle.
Basically I would love to have a generation guy blaine with articulation and the new neck, but Tango seems like an acceptable substitute.
