GC 2007: Operation Flashpoint sequel video—in-game or not?

There’s another FPS coming to town, and what better venue to show off the latest trailer than the 2007 Leipzig Games Convention in Germany? The game: Operation Flashpoint 2. It’s not exactly new since it’s a sequel, and it was also announced four years ago, but you know what I mean.
If you haven’t heard of the original, then shame on you. The original Operation Flashpoint was a tactical shooter set in the Cold War. Did I mention it had great reviews? The sequel, however, looks like a different beast altogether.
