While the release of Halo 3 saw sales breaking the $300 Million mark, Rockstar Games is expecting to surpass $400 Million in sales with hitmaker Grand Theft Auto IV, hitting stores this week.

Because of the pre-sale programs and long term selling ability, the Grand Theft Auto games (I, II, III, Vice City, IV) are the top sellers in the market despite the M (Mature) Rating and excess violence.
