I think some people lack in perspective and enjoy the moment "bullying".
When first IL2 came out I got it the day of release and play it with a 56k modem. The sim it was and what it has become now there is a huge difference.
With IL2 COD we have to expect samething. I guess, We'll all be able to play it maxed out within a year or so, as with any piece of software it has to be debugged and improved and given the complexity of simulators it's "impossible" to release it and expect it to be bug free or fully optimized.
I have seen some videos showing the damage model and only for that it's a huge leap forward in realism. I hope they have good sales and release new addons with more maps and planes.
Future looks bright too me
