DICE has admitted that as they started focusing on the PC version of Battlefield 3 and as they got closer to release, the studio was forced to drop the PC as the lead platform focus, and instead focus on the console versions of the game to get the game out the door.
The switch to the consoles as the main platform focus was required in order to meet the release date. However, GM Karl-Magnus Troedsson claims that their ambition was to get the absolute most out of each platform for the game. The studio is pleased with the end result.
