Batman: Arkham City collector’s edition now official

As we expected yesterday, when the Batman: Arkham City collector’s edition was sighted online, official details have now been released.
There are a couple of additions to the information already revealed. First, the collector’s edition will also come with a code for redeeming a digital version of a Batman: Arkham City album, featuring “original songs by hit artists” (though no further details on who those artists may be). Secondly, the DLC that collector’s edition buyers will have early access to will be the “Iceberg Lounge Challenge Map” and a Batman: The Dark Knight Returns skin.
Otherwise, it’s as reported; a Kotobukiya Batman statue, an art book and the Gotham Knight animations. All for $100 USD.
Take a look at the PS3 version of the bundle, below.
