Battlefield 3 suffered a bit of a misfire at launch last month due to technical woes that DICE was working to address even before the game hit stores, as evidence by the sizable day one patch that the game received. Another patch is coming this week, the developer confirms on the Battlefield Blog, a "significant" one that hits PCs first and consoles as soon as it cycle through the Microsoft and Sony certification processes.
There's not much in the way of specific detail on what the patch address, though you can expect to see "improved polish, stability, weapons balancing, squad control functionality, user interface enhancements and several feature enhancements," as well as the removal of "negative mouse acceleration."
DICE also encourages continued diligence with regards to reporting cheaters and boosters, though there's no mention in the post of specific cheat-friendly glitches being addressed by next week's update.
