In early 2007, the Sigma Six name was dropped from the merchandise in favor of just "GI Joe". Which means, at minimum, this product is 3 years old. Hasbro does not just have that kind of stock sitting around for that long, it would have ended up at a discount venue long before now.
And more importantly, aside from the 2.5 figure sets (which may well have been a "lost case"), if stores were still getting cases of Sigma Six, they'd have more than just army builders there. That says to me it was a collector returning stuff he had laying around.
