The Battlefield Blog outlines scheduled maintenance planned in the wee hours of tomorrow morning for Battlefield Bad Company 2 on Windows, Xbox 360, and PlayStation 3. This will take place between 5:00 am and 8:00 am EST. Word is: "The purpose is to improve performance of the stats system, to reduce/eliminate stats outages. We're very sorry for the inconvenience." There's a related update on the Electronic Arts UK Forums with details on how the stats backend works on all three platforms.
