All of them.
 
EDIT: Picked B though, only one I can recall playing (mainly a rush man) which must mean that it is the one I prefer.

I think Panama canal would be great. now that i thought about it laguna alta would be amazing too.Also Atacama would be cool if both sides got apaches.

I was having trouble deciding between Atacama and Panama, but I think Panama would be cool with all the ruble and the ships. I would love to play on Atacama too... the first 4 crates could be in the town near RU base. The next set could be across the gap of desert and in  both sides of the ship, and the last set could be in the final town.

laguna alta  damn that is such a good map

I really just want Atacama Desert. There aren't really any desert maps except for Arica Harbor which quickly turns into more industrial or urban area. But it's a good map nonetheless. I like maps in my games to feel like they follow on from one another. I like the thought that Arica Harbor isn't that far from Atacama Desert and stuff. It gives a feeling of continuity and more realism in my book. I know people will disagree with this, but I find it's a nice way to make the online feel more alive.

arica harbour is the worst map by a country mile, the only decent bit of it is where you are in squad DM 
the open bit is boring as hell

I'd like to see a new map actually. 

I'm still waiting for the FIRST map pack.
 
Maps that come with the retail copy of the game (ie, MAP PACK 1) don't count. Maps that aren't new maps, but just have bombs instead of flags or flags instead of bombs don't count. They may think they're on "MAP PACK 2" as of the 30th, but as far as I am concerned, we're still on "original release date game content that came on the disk".

I didn't vote.  But I want all maps to be on rush mode because I really don't like conquest anymore.  I like the way rush moves you around the map and controls the pace of the game more.  The new rush map we have feels completely different than when its played conquest style.  There map design is truly state of the art.  Except for Arica Harbor.  That map pretty much blows in both Conquest and Rush.

Ghost Town.

I want the one they showed in the commercial on TV that was all urban and the russians were in that open buggy with the mounted machine gun on it. That would be awesome.

Why can't we have new maps?

" Why can't we have new maps? "

Dragon Valley

" Dragon Valley "

OASIS.

I would do (almost) anything to have Harvest Day brought back.

Atacama is my favorite map, but I don't think it would make a good rush map. The defending team could just sit back and pick off the attackers as they pass through the giant open zones between A, B, and C. I voted for White Pass.

You know what would be cool?
 
A rush map in an urban area.

Overgrown and the other map that were remade for the modern warfare 2 stimulus package, just to blow them apart cause they're only one town around an objective.

Atacama Desert is my favourite map, so I choose that.

" OASIS. "

White Pass all the way.

Haven't played all of them, but I played a bit of atacama and I love Arica Harbour so I really want that in rush too :D
