DBPro X10 will have DirectX10, but it won't be an update, it'll be like FPSC and FPSC X10. I've no idea when it comes out.

I'm certain the answer is no. I'm not Lee or Rick or Mike, but I'm sure of my answer. But in any case, it would probably just be the engine code, as all of the scripts and variables are in separate INI files and the like.
