I know a whole bunch of guns they should include and since the weapon list hasnt been confirmed they could be anything. I know i would like to see the...
-G3 Rifle
-M16A4 (upgraded M16A3, longer range, quicker fire rate)
-M249 (faster rate of fire than the MK.4

-AK-105
and
-Some more sniper rifles (not OSOK)
-A decent MG for the terrs (fast fire rate and 100 round clip)
A good terr. MG should be avaliable thorugh the new customisation interface on SCA
Also i would like to see more equip slots and more attachment slots.
