DC Collectibles' Arkham City line has been an incredible success for the re-branded manufacturer. And they don't seem to be dropping the property anytime soon, with a pair of brand new two-packs on the way.

There have been an impressive number of releases in the Arkham Asylum and Arkham City franchises, and collectors will have some additional figures to add to their displays in the near future. Fans of the twin behemoths Mr. Hammer and Sickle will be relieved to finally see this duo in plastic, as the new images from DC Collectibles reveal below.

I love that these characters are being created, but this release strategy from DC Collectibles is questionable at best and practically malicious at worst. Penguin and Harley Quinn have already been released and a vast majority of this line's collectors already have those figures. But in order to milk an additional two-pack sale out of devoted followers, DC Collectibles has split the naturally-paired never-made characters across two different purchases. This allows them to effectively charge double for the new figures while tossing in a cheap token figure to explain away the cost.

If that was the only way these figures could be produced, so be it. But it has left a foul taste in a lot of potential buyers' mouths. I wonder if these characters are important enough for DC Collectibles' calculated risk to actually pay off. I can imagine a lot of people simply passing on them due to prohibitive costs, which might negatively impact the future of the line.

Regardless of the iffy sales strategy, the figures themselves look pretty good. They're plenty big, the accessories are spot-on, and the sculpts are detailed and expressive. For anyone who happens to be missing Harley Quinn and the Penguin, these are practically required purchases. For everyone else, it might just be a pill too big to swallow.
