It seems the guys over at OffDutyGamers managed to get ahold of the developers who are working on Battlefield 3.

This is what they were able to get out of them.

• Squad Leader confirmed, 4 Person Squad
• Ability to spot a Enemy Squad Leader
• Equippable Grenades
• Falling debris from destruction 3.0 can kill players!
• Equippable knife as well as quick knife (like BC2)
• Support class able to mount bipods and give ammo
• Rifleman class has medpack + defibrillator
• Ability to change fire modes in multiplayer (semi/burst/auto)
• Regenerative health in MP, but suppression effect stops regen (only regen when you aren’t under fire)
• Suppression effects from LMG, blur vision
• Flashlights can blind the enemy
• First Person Animations in Multiplayer
• Faction Specific Weapons + Unlocks
• Vehicles can be immobilized before being destroyed
