I am doing all of this from my phone, but I cannot embed the video. If someone could please embed it below my post it would be appreciated.

These images are loading screens from VIP MP7 and BC2: Vietnam. They were found in the latest PC patch.

Two of the Vietnam maps shown are unannounced.

I just whipped out my iPhone 4 and made this video. Enjoy.

Oasis should be awesome.

Are the first ones before the Vietnam stuff come from Bad Company 1?  If so, FUCK YES!!! 
 
I still want to see how Strike at Karkand would play with Frostbite.

Oh, here is the description for the video:
These are the 9 upcoming maps for Battlefield: Bad Company 2. By "maps" I mean geographic locations. For example, harvest day will support rush and conquest, but it is still the same map.

In order of appearance: 
VIP Map Pack # 7.
Price: free
Date: unknown
Maps:
-Harvest Day (rush, conquest)
-Oasis (rush, conquest)

-Heavy Metal (conquest)

----------------------------

Bad Company 2 Vietnam: 
Price: $14.99

Maps:
-Phu Bai Valley (conquest confirmed)

I sure love me some snow maps. Might just be enough to get me back into the game after months of absence.
