According to CVG, Eidos plans to release a Batman Arkham Asylum Game of the Year edition in late March (although admits this may have been pushed back) complete with new 3D gameplay on consoles.
An add for the game in India reveals the re-release will include Trioviz 3D technology and two sets of 3D glasses on Xbox 360 and PS3. The GOTY edition will also feature six extra challenge maps, some of which have already been made available as DLC.

Crime Alley Challenge Map: A combat map set in this iconic location from Gotham City that has been overrun by The Joker's henchmen.
Totally Insane Challenge Map: A combat map set in the heart of Arkham Asylum where players will need to fight against waves of lunatics.
Nocturnal Hunter Challenge Map: an Invisible Predator map where players will need to seize back control of the Prison Watchtowers from The Joker's henchmen.
