Looks like Eidos and Rocksteady Studios are planning to celebrate the success of Batman: Arkham Asylum with a Game Of The Year edition if the BBFC's rating site is anything to go by (which it is).
You've got to think that the final package will include the original game and all the DLC though. but we'll have to wait for Eidos to announce its existence first.
In case you're not up to speed, a sequel was announced at the back end of last year. Check out the teaser below.
