$100 Batman: Arkham City collector's edition listed on Best Buy

US retailer Best Buy (via CVG) has listed a collector's edition of Batman: Arkham City. And that's actually all she wrote, literally: there's not much else mentioned on the CE, such as its contents. Just that it's a CE and it'll set you back $99.99. We'll look into it with Warner now.

Watch the newest trailer for the Rocksteady actioner here. Game's out in October.
