You know, I have heard stuff about stories similar to this.  Many times the developers want their DLC to be free and yet, M$ would end up selling it for a nice profit on XBL, sometimes splitting the bigger stuff into 2 DLs for same price each.  I remember hearing about this when the Gears maps came out.  M$ compromised and just had the maps on sale for about 2 months, and THEN put them out for free.  However, I know I remember hearing similar stories in the past.  I'd LOVE to be able to think forward about a game purchase before purchasing it vs another similar or equally appetizing title to decide which would get me more play and content, meaning that would give me more for the price I would be paying for this title vs the other.  Now, I just got to decide which will get me the more content, and hope I can afford to pay for each extra content when I want it, or I got to weigh the ending result after all DLC is added vs price, making everything a lot more complicated.  I doubt it'll ever be that way though.
