Forgotten? No.
But you are right nevertheless.
It will be boring shortly after the release, infact VERY shortly after that, because no matter how good the game will be, it won't please the crowds.
It won't turn out into settling the game on the shelves, though, but in demanding more patches, more planes, more maps, more options, more eyecandy, etc. Just like it was with every release and every patch for IL2. And since the first release will "only" model the Battle of Britain, people will cry out suffering in pain and ask why, oh why they should buy the title if plane xy is not included. Again, just like it was in the days of IL2.
And even though they were told over and over again, that this is only the start into a new era of game-engine, covering all theaters from WW1 to Korea and later, they will cry out still.
I doubt that the crowds will momentarily grow up the moment BoB is released.
