S!
Well in that Stuka picture in bottom with window damage and seeing ground below..there are purple buildings and it clearly tells the game engine is not finished yet
We get these anomalies in IL2 if drivers or similar are not OK
I would guess Oleg will drop a "SoW Bomb" a bit before release, to make people drool and anticipate it. He is good in this kind of stuff
Before that the regular updates keep coming and possibly now and then some hints and tips for what to wait
As IceFire said, there is a point how much you want to detail things. How much is useful and meaningful as overdoing it just wastes resources that could be used elsewhere. Balance in everything. And snipping off something not really needed from somewhere can free resources to add something more in fidelity elsewhere...
But SoW will be a benchmark on it's own as IL-2 was 2001. And as you see, IL2 still goes strong at age of 10 years
So what can we expect from SoW..SoW:MTO, SoW
TO, SoW:KTO?
