This is not going to come out for quite a while, if you ask me.
Just FYI, as a lot of people seem to not be aware of, there is a very good, mature sim about the Battle of Britain, and no matter how good SoW is going to become, it's hard to imagine that it will surpass BoB2 in every aspect, especially the strategic level / AI.
Recently I wrote a thread about exactly this game:
