August software sales figures have just been released by the NPD Group, showing that EA's venerable football franchise shows no signs of slowing down, just like John Madden at a buffet table. The Xbox 360 SKU crushed the competition, beating out the PlayStation 2 version by an additional 250,000 units sold. Some 2 million-plus units of Madden NFL 08 were sold across all platforms.

Sales of the Xbox 360 critical darling BioShock outsold its first person competition Metroid Prime 3: Corruption by more than two-to-one during the month of August. Keep in mind the latter was on the market for one less week than 2K's insta-hit, but it still bodes well for a BioShock sequel.
