So Hasbro cancelled his re-release?
Well, not exactly
It is important to note that the best opportunity to obtain these special edition figures is at the convention itself.
While we cannot guarantee anything at this time, because of the demand by fans who could not get the Comic-Con figures, we are looking at making the Sgt. Slaughter figures available again at retail, albeit in different packaging and likely not as single-carded basic figures. While details are not final we are making progress for late Spring ’11 and will have news in a couple months. We look forward to updating you then.
Bolded emphasis Hasbro's; underlined emphasis mine. They never said he was going to be released again, so there was nothing to cancel. They said they were looking at
getting him out there again.
