I thought an oil rig level like in the single player level would be awesome...

The Moon!!

Charging $5 for it to make up for the $15 they charged for the first one.

yeah, i've got a great idea. Not charging 15$ so I might actually consider buying it.

You know the level where you're in space? Need I say more...

Like others have said, next map pack needs to be, IN SPAAAAACE!!!

Needs to take place in an area in Washington.

Crossfire with a Christmas theme. Christmas Trees and snow everywhere. Would be pretty epic.

The white house, its all indoors.
 
Or........
 
Cape Canaveral, think about it.

If they bring two more CoD4 maps, I hope they bring Broadcast(The TV station one, I think it's called that...) and Crossfire or Backlot.  For new maps, I would want a CQC white house level, an Oil Rig level, and a level based on the Gulag prison thing or one with a "generic American downtown" theme, like the Burgertown level.

A space station or oil rig

Burger Town and Oil Rig would be cool

They should do Blood Gulch MW2 style.

The facility map from Goldeneye

The shopping outlet (i.e. Burger Town) would make an awesome objective based map. Fighting in front of The Capitol Building or in those government buildings surrounding it in multiplayer would also be awesome, mostly because it was the only moment in MW2 that actually got more out of me than "I guess that was badass." The caves you fight in towards the end of the level would also be an interesting indoor map. As far as flashback maps, the school and the construction site from CoD4 need to be brought back.

wake island....

Refrigerator Warehouse

I also vote Space, even though I'll never play it.

Why not make one map in the DC area right after the EMP has hit. I mean the level in singleplayer that looks the most interesting should be in the multiplayer as well. Although I hate the rain but think about it, no lights just fire and roaring thunderstorms. If you think about it where the hell is night vision in this game 'cause it would be perfect for that level.
 
Oil rig also sounds perfect.

one word - VACANT.

It'll probably like the last one with a mix of old and new maps. But if I could have ANY map, it would be a hangar filled with watermelons. hehe. They were fun to shoot.

I think the shopping district, with the Nova Gas Station, Burger Town and the rest of those stores would be pretty good. It's a big enough area for it and it's very open except for the buildings. But I'd also like to see the White House from the campaign as well. That would be so fun to play on those maps I think.
