Ok, so after about a half hour of waiting, I finally got to watch the 2 1/2-minute-long Fallout 3 Teaser Trailer. While there wasn't much of it, what was there was nice. It seems to me that the feeling and atmosphere are spot-on, and the graphics and sound/music quality are just what I was expecting. I would have liked to see more, but for a teaser, it was pretty decent.
Update: I guess I should have mentioned that the teaser does give us a projected release date - Fall 2008. Not exactly "Coming Soon," but I'm still looking forward to it.
