Foobar,
that map in olegs recent screenshot might more or less be it, or maybe just a little bigger
on the south east you can see the first 1/2 of belgian coast (and oleg said holland would not be included), on the english coast going north i would have expected the map to at least go to norwich (norfolk) and it looks like on olegs small map it does (not on yours) but since we cant attack that far from the closer dutch bases (as germans) we probably wont bother flying from calais all the way that far north anyway.
the french and brittish coasts will probably extend a little further west i suspect then what you see on your map you posted, perhaps another 25% ?
i dont see a problem with a map that size, if it is 1:1 in size it will take enough time to fly from france to england, or for english squadrons to try and scramble and intercept at the right altitudes.
add to that a 24/7 dynamic campaign engine, high detail visuals in new gfx engine, missions that involve fighter vs fighter, defending/attacking bombers, attacking/defending shipping, ability to pilot small coastal vessels and some vehicles,........... and i think you already have a massive game to start with
6/12 later oleg probably will release a new theater area, like the med or north africa, and another area 6 or 12 months later etc
enough to keep me happy
