Well I've always wondered about the 50million figure. People say you could fund two or three games with that money, and it almost looks like thats what MS did, they funded two more GTAIV games. Rockstar would have a bit left over from the $50million due to the game engine already being up and running making the expansions cheaper, and they would have discretion over DLC pricing.
