There's a live Q+A on at the moment, it's in German, the English one is tomorrow. link
I've asked about MEC and was told that they are NOT in - the remakes of Karkand and Kubra feature US and Russian forces. I also asked how integrated Origin and Battlelog are, and the answer wasn't that clear, I took it to mean that you can access Battlelog through Origin, but you don't have to.
There is no in-game server browser. Getting to a server is done via your browser + battlelog. You can alt+tab to get there, or you can exit the game. Exiting and loading the game is apparently very quick as there will be no intro videos!
That's... Bizarre. Because those other screens posted before do not look like Russian uniforms that I've seen. Given the similarity between them and the look of MEC in prior battlefield games, I simply assumed that's what it was.
I mean those guys don't even LOOK Russian\eastern european.
I'm not referring to the chaps in front getting shot at in those photos (with the balaclavas), as they do appear to be Russian. But the guys in the background with the facial hair and helmets..
Is it possible that level has Russians teaming up with some kind of local government force to combat the Americans?
