According to the trailer itself, there will be four Battlefield 2 maps reimagined in Frostbite 2 (Strike at Karkand, Sharqi Peninsula, Gulf of Oman and Wake Island), 10 new weapons, 3 new vehicles, and enhanced destruction and persistence, and shall be released this December (as hinted on the Limited Edition copies).
As a reminder, I should say who pre-ordered Battlefield 3 and got the Limited Edition copy will receive Back to Karkand at no extra charge, while who bought the Standard Edition will have to purchase it on the proper digital distributor for $14,99.
