We already know how impressive Metal Gear Solid 4 can be. The previous trailers have been in real-time, but they haven't represented actual gameplay. Now Kojima's ready to blow our socks off with some in-game footage mixed in with new cutscenes. Always the showman, we expect the new teaser to be in the traditional Kojima mold - a little bit of humor, a little bit of melodrama, incredible style, and lots of kicking ass.
If we can get our hands on the footage somehow, expect us to post it ASAP.
