Different Disks, Problem or Glitch?

It had to have been updated. That kind of thing just doesn't happen. The software has to be different. Have you noticed anything else? Like requirements for unlocks have changed? Is there a custom stick setup in the controller options menu?

I don't think they update "versions" on games, do they? I mean, it's impossible to tell if they updated the game, right? Like a rev letter on the package or disk.

Another thing. I was at Best Buy last night and I noticed they had two slots full of new IL-2 games. I was just there several times over the holidays and there were none. So it appears new games have been shipped. I wonder if they updated the game software in lieu of putting out a patch. They wouldn't do that, right?
