Received some updated information (screenshot above) on the release date of Target's Exclusive Black Series 6-Inch Gamorrean Guard. Per my local Texas store the expected arrival date is 7/20. Some stores may received them a little earlier or later, depending on where your local store falls in the distribution chain.
Also according to their system there is a new planogram that is scheduled to be set by 7/29, which includes the Gamorrean Guard.
Please remember that these updated dates are subject to change and may not reflect the release dates on target.com.
