Is grand theft auto 4 the ballad of gay tony coming out on disc format?

It is available as part of Grand Theft Auto: Episodes From Liberty City for the Xbox 360® video game and entertainment system from Microsoft exclusively. For the first time, players can purchase The Lost and Damned and The Ballad of Gay Tony, two complete games, together on a single disc as Grand Theft Auto: Episodes From Liberty City. The disc-based offering does not require Internet connectivity or a copy of Grand Theft Auto IV.

NEWS UPDATE:

In case this is of interest to you, I have just read an item that announces Episodes from Liberty City (previously an Xbox 360 exclusive) is to be apparently available for PS3 and PC on 30th March this year.
