Rocksteady working on game for next gen Sony system

Arkham Asylum and Arkham City developers are hard at work on on a game for the next gen Sony system in their London studios as we speak ( well, it's midnight so probably not..)

A developer has confirmed to my source that since August this year they were given the new Sony hardware and have been hard at work on an unconfirmed title ever since. Sony apparently take the security of their next gen dev kits incredibly seriously and even asked Rocksteady for an entire floor plan just so they could be sure of it's whereabouts at all times.

My source should be speaking with the developer in the coming weeks so I will try and get some more info as soon as I can.
