Ok, so that's the list that's floating around. Here is my analysis. Plaza 2? I think this could be Plaza v2.0 and therefor just be called Plaza. I'm not convinced on the names for Alpha and Bravo. I'm also unsure about Hardhat. So from free mw3 map packs, This is my list of predicted maps for Call of Duty: Modern Warfare 3:
Alps - A semi-large map similar to Derail on MW2
Bootleg - A CQB map in a smuggling warehouse?
Brooklyn - A medium sized map similar to Skidrow and Invasion in MW2
Carbon - I honestly have no clue.
Coast - I'm guessing a modern normandy beach landing type deal. Map design similar to something from WW2 games but obviously tech'd up to modern specs.
Dome - This i'm guessing will be a primarily indoors map similar size to Terminal from MW2.
Exchange - I have had multiple theories for this map. I would say this map is similar to berlin wall perhaps from black ops in that it the frontline of both factions.
Interange - Could this be a typo for interchange? Possibly a train station? similar size to Estate on MW2?
Lambeth - This has to be medium-large map. I think this will be a 3 level map. The buildings and rooftops, the ground and possibly some access to the london underground.
Meteroa - Again I think this is a typo for Meteora. This is think will be a very CQB map fought inside the monastry in Greece perhaps? It has a very secluded outer-map and looks very CoD.
Mogadishu - For this map i'm speculating a very close match to Favela from MW2. Mogadishu also suggests that there could be references to Somalia's most notorious islamic rebel group, al-Shabaab.
Paris - There are so many locations within Paris that this map could feature. My personal guess is it will be centered around either the arc de triomphe or the Eiffel Tower.
Plaza - For plaza i'm guessing something similar to the Invasion map in MW2 but with a twist of showdown from CoD4.
Radar - On this i'm seeing something like a cross between array on Black Ops and De-rail on MW2. Perhaps with a more indoor element?
Seatown - A beach town i'm guessing similar to Nuketown on Black ops but with more buildings?
Underground - This could be like what i've suggested for Lambeth with a lot of access to underground tunnels etc. So I'm not sure is what i'm saying.
Village - Well the name speaks for itself. The question is where? What culture will the village be set in? I'm thinking either African or East-Asian.
Ok so that was the Free MW3 Maps on the fly rundown of the new maps for MW3.
