I am a native German speaker, so I can tell you what the trailer says:
1. Yes, it's from a German magazine, not an official trailer.
2. The moves are just an extra - they say there are over 200 victory moves, and they wanted to show some of them in the warm-up phase of the round.
3. They say the game is much more tactical than BF1942 and others. You have to rely on the team. It's aimed at Clan and other hardcore players and might frustrate casual gamers.
4. There are over 70 vehicles.
5. The outdoor locations are huge, much larger than anything in other games.
6. Everyhing is destroyable. Buildings, trees, even the ground deforms from grenade explosions.
That's all I remember without watching it again
