One must remember that when IL2 was released the internet was dial-up in moost countries and magazine marketing was the way to go...
With the advent of superfast broadband you can build the hype around the sim within weeks rather than what took months before.
I firmly believe he is still on track for a late September release.
If one looks at both ROF and Silenthunter 5, both were hyped withing a weeks. In fact the Silenthunter 5 site was created about two months before launch if not less.
I agree with one of the posters in this thread that pointed to mission building, ai and graphic tweaking as being what is left to do.
The flight models will not change much from IL2, Oleg has already said this, just a few tweaks.
A lot of what we are seeing in TD's 2.10 patch may be closet tests of the SOW ai.
An ai that cannot see through clouds or will not shoot at a friendly plane... The list is endless but I have to believe the advances in ai shows a close colaberation between the SOW team and TD
