So after some searching I came across a very interesting fact.
IW held a contest for PC gamers to create new maps for MW. The maps would be sent in and they would name their winners. It appears that winners were never announced. There were also problems with the contest as the submit dates were changed up and no one was notified.
I first learned of this here:

Here are the images posted from that link.
Now they are not exact. But from what I believe, IW took the original COD4 map and "lightened" it for the consoles. But the design is uncanny. Now remember, these images are from the same map just looking at different points. From a design perspective it would near impossible to recreate this either from memory or by guessing. The intent of the MW2 is clearly copied.
...or stolen.
Here's the famous IW community manager himself... no notice of winner on his blog.

This link shows the original notice that is no longer available on IW's site.

If you look at the 3rd post down on this page; this was spot on!!!

So. Contest went up. People made maps. No winners. Maps added to MW2.
Its really frustrating to the PC community, because they steal the mods made from COD4 and use them in MW2, but do not allow for any new modding to happen in MW2. Its kinda like saying, "Thanks for the sweat and history PC. See ya later!"
Thanks IW for stealing from the PC community to give to the world. At least say thank you after the rape.
But no not everything I wrote was false. Where are the winners to the contest, what happened with it? Where were the submitted maps used.
Something to keep in mind.
