Carenado are currently working on the Socata TBM-850 aircraft for X-Plane. To show of their progress they have posted some preview images of the work-in-progress, and it looks stunning. Not sure if any image altering applications were used, but the sharpness of textures and the quality of colors are magnificent. Judge for yourself!
Before you ask, no release date was announced, but it looks to be a project that is at a fairly advanced stage.
