Someone posted this on the UK General Xbox Discossion's Battlefield 3 thread.
Thought I'd share.
In a nutshell, the FAMAS is getting buffed (yeah, you read that right BUFFED) and the PDW's will get NERFED.
G3A3 is getting buffed.
Most of the LMGs are having their minimum damage buffed.
M98B is getting nerfed.
12G Slug ammo is getting buffed
12G Buckshot/Flechette ammo is getting nerfed (to stupidity Buckshot is going from 20 max damage to 12.4 but they buffed the range so it's cool...not)
It's not the full list and it might change, but it gives a good idea of what DICE are doing....breaking the game more.
