I want evidence, not a " I think" story. Even if it from god directly, it would still be nothing more then a pr story. Evidence please, it can´t be so hard since everyone claims to know everything about it.The forums are full of know it alls on the gGTA dlc here, give me the simple evidence!

Here's an interview that should clear it up.

"I think the mission packs with the episodes are going to be pretty deep, offering another full-on adventure in this world," he told Edge. "I think we will be in a position to market them not a million miles away from the way the boxed game is marketed."

Assuming people like the game then Houser's sense is that they'll probably like the episodes too, he says.

"And if they like the episodes it will probably make sense to market them aggressively, and we want people to be there on that first day as much as is realistic. Our goal will be to fry those Xbox Live servers - we want to have as many people tune in at that moment as possible."

Don't worry though, the marketing budget isn't going to spawn from your Microsoft Points: "You'll get a lot of content for your money," says Houser. "There are too many stories at the moment of people having the feeling that they're not getting enough for their money in terms of downloadable content.

"I never want people feeling that we've duped them in any way, shape or form. That's something that we've been into from the beginning."

I think the points in bold clear up your questions.

 Yup, but these are good sources. And sometimes, rumours turn out to be true.
