Yeah, more accurate cockpits would be nice. I flew some in Fighter Ace III and the cockpits look closer to the real thing than AH or Warbirds does. I still like AH better though, the flight models, the community and the game all around seemed better.
As long as the download footprint can be kept something reasonable for those players with 56k modems I am all for it. If not, it really doesn't kill the immersion for me.
