'GTA IV' DLC may not arrive this year

A Rockstar executive has revealed that the downloadable content for Grand Theft Auto IV might not make it out this year.

The Xbox 360 exclusive content was pencilled in for an autumn release, but Rockstar's Dan Houser told Variety that the release date is still unknown.

"I'm not sure. It's going well, but we don’t know a date. We hope to be announcing that in the next few weeks. We're still figuring out a few things. We're more focused on quality than dates, always have been," he said.

Microsoft allegedly paid $50 million (£31 million) for the exclusive content. However little is known about what gamers can expect from the downloads, with Houser warning gamers not to "imagine this enormous thing it never can be".
