The past several weeks have seen the downloadable expansions for Grand Theft Auto IV at the center of several rumors. First came a report that The Lost and Damned would be ported to the PlayStation 3--a report Microsoft quickly and unequivocally shot down. "The episodes are exclusive to Xbox 360," the company said flatly.

Just days later, another rumor surfaced that the second, as-yet unnamed Xbox 360 episode would be a pillar of Microsoft's June 1 press conference at the Electronic Entertainment Expo. That piece of scuttlebutt also pegged the game's subtitle as being Blood and a Four Leaf Clover, hinting it would focus on the Irish gangsters known as the MacReary Brothers.

Now, Rockstar Games has announced that it won't be long until it officially unveils the second Xbox 360-exclusive update to Grand Theft Auto IV. The famously tight-lipped development house, owned by Take-Two Interactive, used a forum perfectly suited to its curt approach to game PR--Twitter. "Details on 2nd episode of GTAIV downloadable content coming soon," read a late-Friday post from the publisher, which--by the very nature of the site's format--is limited to 140 characters.

Stay tuned to GameSpot for more information on the second episode of Grand Theft Auto IV.
