I just posted before that Monkey Islan 2 would be available on PSN and MAC but just found out that it will be on XBLA too
LucasArts Games just confirmed via Twitter that Monkey Island 2: LeChuck's Revenge will get the special edition treatment while The Secret of Monkey Island Special Edition comes to PSN and MAC.
Go GUYBRUSH!
UPDATE: LucasArts went on to announce the platforms on which LeChuck will take his revenge. We will see him battle Guybrush on XBLA, PSN, PC, MAC and iPhone!
