In an interview with Variety, Rockstar's Co-Founder and Creative VP Dan Houser said that he's not sure if the eagerly-awaited downloadable content for Grand Theft Auto IV will actually come out this year.
Me [Variety]: On another topic, I have to ask you about the "GTA IV" downloadable content you're doing. Do you still expect that to come out this year?

DH: 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. But the development is going really good. It's shaping up to be something we're very proud of. That was our goal.

Me [Variety]: Do you think you'll talk at all about what the DLC will be and how it will fit into "GTA IV's" story?

DH: We want to give people a rough idea so their expectations are roughly in line. We don't want them to imagine it's this enormous thing that it can never be...

Doing a big digital launch is something we've never done before. It's virgin territory, but at the same time, we feel very exposed because there's no case history. No one ever came out with major DLC for a major game like this before.

It's new territory for everybody. We're making it up a little bit as we go along. That's always fun, but it makes you nervous.
Along with the release date, details surrounding pricing and content for the upcoming DLC still remain unknown.
