Well, I think if FSX keeps the compatibility to our current models, it means the painting technology does not change at all, or too much. The new DirectX features some helpful things, like dynamic shadows, and better dynamic shine, better reflections. I have red that some painters are already afraid, that graphic engines will be so good, that many current painting technic will be unnecessary, and the painting itself will became a boring process to do in the future.
So the answer is yes. I believe we can still be able to paint our own fleet in FSX
