Wow. How out of touch some of us tend to be .... All of the dolls are on sale now on the website and have been for at least a week when I noticed it ..... I don't see a link for Alexie but the other 2 are there... I just got mine yesterday..
The official (delayed) release for the other 3 dolls was announced on twitter to be September 2014 (see July 9 twits): https://twitter.com/oneworlddolls .
Quality Stocks posted that the yet again "official" release of these 3 new dolls will be at ToyFair 2015 (February) - just in time for the 2014 Christmas....er....2015 Easter Doll season!
The other 3 dolls are not available on ToysRUs, Wayfair, Sears, HEB, or Doll Genie. Doll Genie is the only one that actually advertises these other 3 dolls, but states that they are "out of stock" - Trent may wish to dig some more inventory out of the basement to replenish this important distributor: https://www.dollgenie.com/index.php?collection=35
Regarding the official OWOO website, they state that these three dolls are "coming soon" (scroll over "The Dolls": http://oneworlddolls.com/ ). Which is interesting since the Dahlia and Kamini dolls are actually shown for sale - so much for the grand introduction at ToyFair 2015....
