Both, which have been Xbox 360 exclusives until now, will be arriving for PS3 and PC. The Lost and Damned and The Ballad of Gay Tony.
The exclusivity deal with Microsoft was just a timed one, and ultimately proved a little sore for Rockstar as sales didn't quite match up to expectations. PC gamers already knew they'd be getting Lost and Damned as an update adding achievement support.
Grand Theft Auto IV's Episodes from Liberty City will hit PS3 and PC sometime in March, available over the PlayStation Store, Games for Windows Live and in shops.
