Found this on another site. Personally I am taking it with a grain of salt.

Hasbro responds to "Slaughter Gate" : Crimson Monkey

 

Hope this is true.

 

that post was from July 30th, we still don't have actual confirmation that we will get more

 

I don't think HTS will have any more Sarges until they put up the AFA ones. A quote from the Slaughter-Con/HTS.com thread on hisstank:

 

This sounds like something Hasbro would do. When I sent in for the mail-away Indiana Jones figure back when they were doing that promo, I got a letter saying they had run out of stock of the mail-away figure. But, they will be doing another run of them soon to fill in the other orders. And they did. About a month later, I got my mail-away figure. Hasbro honored their promo that time, and I feel they will honor the demands that fans want Sgt. Slaughter. They know he's a popular figure and a sure seller, so their is definite profit for them here. I don't know about others, but I'm going to keep an eye out for him now.   Best of luck to all who want one as I hope people who couldn't go to SDCC (like me) can get him through HTS.
