Interesting - do you know why SOW has been pushed back for so long?
No?
Because of AEP, PacificFighters, PE2, 1946, loads of free patches and free addons. And you want another addon, so you have something to do while waiting? Makes no sense to me, as you'll wait a lot longer if they do another addon.
And BTW. Maps were not a big problem with IL2. Making them in a way that the minimum requirements for the latest official release-version was and that goal was not met by the mods either. The maps are great, no doubt, but I don't recommend to run them on a machine that meets the minimum specifications for 1946
