ToyArk.com just the other day, and was originally shown on the Funko POP vinyl figures Facebook fanpage.
No word on a release date or pics of the finished piece (or early samples sent generously to Toyriffic by Funko employee extraordinaire Reis who SHOULD HAVE TOLD ME THIS WAS HAPPENING!), but it seems clear they are going with Harley's classic costume look (thank goodness!)
I'll be sure to keep everyone posted on this one when I learn more...REIS!!!!
