I play Il2 1946 on the PC anyway, but I'm looking forward to Birds of Prey because it will give me a chance to play Il2 with my Xbox Live friends. I'm not really that bothered about precisely which Spitfires are in the game, but I would like one Griffon engined Spit and the XIV seems the obvious choice.
BTW, my girlfriend is Canadian, not German, and to follow to your suggestion she would need to get the other tattoo already there removed
