I think the best part about Battlefield 2 was it wasn't just Russians vs Americans. You had (Including SpecForces) U.S, MEC, U.K, China, Insurgents, Rebels and Russians, EU is included to with the now free DLC.
What different factions, and how many do you think would appear in Battlefield 3? Will we be doomed to Russia vs US?  Better yet, what do you think about unique weapons for each of the factions, unlocks and originals?
 
 
Fuck, I hope they have different weapons. I remember the Spetsnaz and the Insurgents, MEC and Rebels all had the same weapons. That was dissapointing as fuck.

I think both Orcs and Orks are a must. Orques would be cool, too.

America vs. Terrorists

MEC, NATO, Russia, China.

this is a good fucking questions 
  I DO NOT want to kill anymore Russians, Arabs, Russians, Russians, Arabs, or Japs 
 
 
Chinese is good because its old-school Battlefield and they havent been used to death  
  
And create fictional conflicts in these countries :   
 

• South America =>  Cuba or Venezuela ? 
• never-used-before Asian countries like... Turkey ? 
•  Europe => Sweden or Italy ? 
• Africa => Sudan / Zaire / Niger ? 

Well I want the American forces there.  
 
British SAS from BF2 was awesome. Love British military lingo.
 
I don't mind Russians or Arabs but I'm tired of them from being in most games lately.
China is a nice one, possibly Korea. 
 
European NATO forces going full force. Doesn't have to be very realistic in my book.
 
A south American force is also of high interest to me.

I don't care which ones in particular, as long as more than two can duke it out at a time on a map.
 
I kinda like fake ones formed from many real countries like 2142 had the Pan Asian Coalition (PAC). But the English VO option needs to keep the accents instead of just being replaced with the native English speaking team's VO.

Nazis are the best enemy to shoot ever but don't fit in a modern setting, I have no reason to hate Russians in this post Cold War world so they're out, random latin american militia is just weird, even though MW2 and BC2 decided to make them enemies, and OPFOR is overdone.
 
I liked fighting China in BF2 though.  They need to be in there. Maybe an enemy PMC or something?

America vs... America! Because you know,  SPOILER WARNING: Click here to reveal hidden content.

nepal, azerbaijan, zanzibar

Have America fight Western Europe, it's basically the last taboo.

" @Ahmad_Metallic: It's kind of weird to have countries like Sweden to duke it out with the PLA isn't it? "

Maybe a PMC group? 
 
It seems all the rage nowadays.

" Maybe a PMC group?  It seems all the rage nowadays. "

San Marino vs Monaco.

" @animateria said:

PMC ? "

The Union vs. The Confederacy.

Russian and American armies are a given. I would like to see a different Arabian army approach than BF2, instead of MEC, let's have a real collation that does exits in the real world. Saudi Arabia is what comes first to my mind since it does have a solid Military Firepower. 
 
Other suggestions would include Turkey, Iran, it all depends on how will DICE set the idea of a global scale war and their locations.
 
On a side note, the voice acting of the Arab MEC Forces was horrid and linguistically incorrect. Doubt they are going to fix it but it's worth noting.

here's a crazy idead: no americas

India vs. Pakistan conflict, with US supporting India and China supporting Pakistan.

that sounds pretty sweet 
 

" On a side note, the voice acting of the Arab MEC Forces was horrid and linguistically incorrect. Doubt they are going to fix it but it's worth noting. "

if i had to name 3 games where the Arabic voice acting was as genuine and real as it gets, they'd be Assassin's Creed, Splinter Cell Conviction and Battlefield 2 !  are you kidding me, bro ? first time i played Battlefield 2, i spammed those arabic commands for several minutes because they sounded so real !  "olqeyat qonbola" CHECK ! "Shukran" Check !  "a7tajo ela mos3ef" check !etc..   Also, the commander voice that kept shouting and encouraging and shit. when he said "Innana na5sarol m3raka, ebda2 el qetal wa2ella edtararto le2eejad sha5sen qadir 3ala al qetal" THAT WAS THE FINAL BLOW <3So why exactly do u think the arabic in BF2 was bad ? "

Well, we can already guarantee America is in it because well, Americans might cry if they don't win at the end. That and they tend to like starting wars. I guess the only real discussion here is who the enemy will be. Judging by the hint at "multiple unexpected fighting locations", sounds like it will be USA vs Rest of World - which seems accurate.

GDI and NOD

" @Jayross said:

NATO is US, what is MEC? "

" GDI and NOD "

Taliban with jets.

" Taliban with jets. "

India v Pakistan maybe. 
Probably will include China or North Korea vs America or EU. I think since I read the games urban settings are likely (not limited to) NYC, Paris, and Tehran then Iran is a possibility in the Middle East. 

" @Jayross said:

" MEC, NATO, Russia, China. "

NATO is US

only armies that make sense to have the tech on said maps.
i dont wanna be playing as insurgents with jets or crazy brazilian militias with jets

" India v Pakistan maybe. "

Uh, the guys with the guns?

Fuck, I hope they have different weapons. I remember the Spetsnaz and the Insurgents, MEC and Rebels all had the same weapons. That was disappointing.

oh please no faction specific weapons, anytime i play a game that has those i always prefer one team over the other and get all bummed out if im on the team with the guns i dont like

I really hope for a separate EU faction on muliplayer maps. We recently got some nice gear. Tiger helicopter, Leopard 2A7+ MBT, Puma and VCBI IFV's

China, Russia(expand though), SAS, US, NATO, MEC. 
 
I would be happy with that. Bring back the spec ops grappling hook =D

64 players, Huge maps, And ... wait wrong thread.
Americans Vs Terrorists
Or some other name 4 Americans.

Canada vs. Mexico. The battle shall take place on US soil. Whoever wins we lose.

Brits and Germans would be a great addition, I want to drive a leopard II and Challenger II.
