Christmas is over, but here's my list for Santa for 2012
Part 1: Ignoring aircraft which I know to be under development or which others have mentioned.
Germany: Blohm & Voss Bv138
Japan: Kawanishi H6K "Mavis"
United Kingdom: Hawker Typhoon - a real 3d model, not a Frankenplane.
United States: Lockheed PV-1 Ventura/B-34 Lexington/PV-2 Harpoon.
Italy: Savoia-Marchetti SM.82 Cangaruo
France: Potez 63 series.
Soviet Union: Yakovlev Yak-6
Part2: Four more aircraft. Again, ignoring things I know to be under development or which others have mentioned:
Kawasaki Ki-10 Perry - A real version, not a Frankenplane
Yakovlev Yak-2/Yak-4 series
Caproni-Vizzola F.5/F.6/F.7 series
Liore-Nieuport LN.40 series
Part 3: List things the sim is missing in your opinion
One unique or generic OBJECT: More beach/landing zone obstacles - such as "rommelspargel" (posts set at an angle with a teller mine on top to blow up landing craft, posts set upright in open fields with telegraph wire strung between them to damage glid8ers).
Any 2 ships/ship types: More small coastal types and torpedo boats, e.g., Sampans, Minesweepers, patrol boats. If I had to limit it to just two: A generic harbor tug (could double as a minesweeper or sub-chaser) and a British patrol boat (e.g., Vosper 60' MTB).
Any 2 vehicles/vehicle types: Too many missing "soft" vehicles to list just one: Artillery tractors of all nations, trucks for nations that don't have them, more Self-Propelled Artillery. If I had to pick two: British Morris Commercial, Autocarro blindato Fiat 626 NM.
Any 1 Gun/Artillery Piece: Again, too many missing types to specify just one. Most critically lacking are French, Italian or British light AA guns. If I had to choose one: British QF 3.7" AA gun.
Part 4: List Any one AI behaviour or game/FMB coding/Map characteristic you would like changed/modified/adapted
Since this is a wish list, I'd like to see dynamic fuel management. It's never going to happen, though.
Part 5: List one historical skin by aircraft type and time period,unit and/or pilot that you would like to see.
My wish is that for every P-51, Bf-109, Fw-190 or Spitfire skin that skinners produce, they also have to make a skin for a plane that gets no love at all, like the Su-2, B6N, MBR-2 or P-63A. I literally have gigabytes of Bf-109 skins, probably one for every Bf-109 that came off the production lines, but almost nothing for dozens of other planes.
