The PC version might have been pushed back, but Codemasters is still dumping Dirt 2 onto consoles and handhelds in early September.
September 8th is when the next version of Codemastersā venerable rally racing series hits North America, dishing Dirt 2 for the PlayStation 3, Xbox 360, Nintendo Wii, DS, and PlayStation Portable. Three days later the game hits the UK, perhaps because it goes under the name Colin McRae: Dirt 2, which takes slightly longer to type out. The PC version has been pushed to December in order to implement DirectX 11 features.
