And what about Linux? Will the game support OpenGL? I really hope the devs will make the game support Linux natively. I've almost completely converted to Linux this summer and it's great! Vista was the turning point for me. IL2 works quite fine on Wine (a Windows emulator), but I really, really hope you devs can make it available for Linux.
A tip for the devs: Follow the trend as ID Software and Epic Games do!

Edit: For me it's vital with Linux support, because otherwise I'll not buy the game.
