DICE has announced that it will be starting a new weekly Battlefield 3 blog, which will preview upcoming changes currently in the works.
“Come back next week for our brand new “Inside DICE” blog series, featuring regular updates to our fans on the latest news, content plans, updates and upgrades we have planned for Battlefield 3,” the developer posted on the Battlefield 3 blog.

Good on them.  After tons of criticism from the community followed by the threat of a "BF3 blackout day" from Battlefieldo.com DICE got their heads out of their collective asses and will now provide us a weekly BF3 update.  I think this a good move on their part and hopefully the impatience exhibited by a lot of the community will be put to rest.  Hopefully we'll have more news to pass about more additions to the patch next week.  See you on the battlefield.

I know a lot of people have been wondering and asking about where to find the lastest weapons tweaks that will be implemented with the upcoming patch.  Demize99 is giving quantitative data to www.symthic.com so users can see the upcoming changes and how they will affect a weapon or attachment.  The easiest way to see where a change has been made is by noting the orange up or down arrow by the value.  Demize is making a conscious effort to send any updates he has via his twitter to symthic.com so the community is given the most recent data.  As far as map tweaks and bug fixes there is no official list that has published as of yet.  Just some rumors/hints from developers.  I'll keep you posted as I find new information.

Discussion of BF3 Weapon Accessories, and their Futures From Demize99 off of reddit r/battlefield3

I'm working on a retweak of the accessories in the game currently, as I feel the player is limited in choice due to a few accessories being the clear winners in almost all categories. While this unfortunately means nerfing those that are over used, the goal here is to focus on improving the under performing and under used attachments. Additionally it is the intention for an unmodified weapon to offer the best balance of Recoil, Accuracy, and Stealth. Right now this is preliminary, I've already asked for feedback on different attachments, and there's several good threads here and on Battlelog that discuss the weapons. Again, I'm not promising this will go live, and I'm not promising there will be an update, I'm looking for feedback and a discussion.

Thanks, Alan "Demize99" Kertz

Foregrip

The Foregrip is for players who who are in close combat and highly mobile fighting situations. It reduces the horizontal recoil forces that make maintaining a consistant aim on target difficult, however it makes aimed shots more difficult.

+34% reduction in horizontal recoil (adjust based on gun)

-20% penalty to base accuracy when aimed
