I for one hope that besides other things the walking animation has been bettered (or will be in a future patch). While the sprint animation looks great, the walking animation looks a lot like in the mod. I know it's not a showstopper, but those little things always got on my nerves. I remember the rate of weapon bob in CoD which looked crappy. I always had the feeling of floating while playing, and it is very unrealistic to have no to little weapon movement. So those things always disturb me in games. But I know there are far more important problems which need a solution.
By the way, great to hear about the patch and about your future plans. If one has a look over at the IWN forums, the last CoD2 patch seems to have brought more problems than solutions.
