Jade Flashwing is going to be released as a Target exclusive.
The images emerging show the Jade color variant of Flashwing with a 'Only at Target' symbol on the packaging. Target hasn't started selling the figure to the public so for now eBay is your only option.
Rumor has it that Jade Flashwing will appear in the Target weekly flyer releasing on St. Patrick's Day (March 17th 2013). Consider it the luck of the Irish if you find one at a Target near you before St. Patrick's Day.
