These are the final images for the upcoming (and now half named named) "Cutie Marks Set" and.... "whatever ends with pus friends" set. Toywiz had the Zecora set listed a for a September release, so we should see them hit stores soon.
I wonder who will be bundled with who next? They seem to be saving a Fluttershy group for last, so hopefully this means they are giving her a non-Rainbowdash model finally!
Thanks to Karoliina for the heads up, and find the Taobao sales page here.
