Some of the upcoming patch details have leaked out in recent days and it appears that some much needed nerfs will happen.  Most notable is one that addresses mortaring from deployment zones while not being able to be attacked.  They are also nerfing the USAS-12 frag rounds.  Thank God!  Other confirmed fixes are a MAV tweak, M-COM attack and defender ribbon tweaks, a tweak to laser designation, and a suppression ribbon tweak.  There is no info on whether the MAV tweak will address "MAV riding" or killing with the MAV.  Also the M-COM tweaks will make it easier to earn those ribbons.  The same goes for the suppression ribbon.  The laser designation tweak is believed to be a nerf in acquisition range of SOFLAMs and laser painters.  There will be a big announcement this week in New York by EA concerning a DLC for BF3 and a possible subscription plan that EA will deploy along with the DLC much like Call of Duty Elite.  We'll keep you posted with more details as they continue to be made available.

2/16/2012 Update:  I just read a tweet from Gustav Halling, Core Designer as DICE,  stating that he has tweaked the Havoc for the upcoming major patch.  This was in response to a fan tweet asking to make the Havoc and Viper handle the same.  So hopefully this tweak will make the Havoc more maneuverable.  Still no word on when the patch will be released.
