Just some of the cool new stuff:
"Photoshop CS4 Extended includes all the new features of Photoshop CS4 plus the ability to manipulate 3D imagery easier than ever before. Now, creativity knows no bounds, as users can paint directly on 3D models and surfaces, merge 2-D files onto 3D images and animate 3D objects. The 3D engine has been rebuilt from the ground up to provide faster performance, allow editing of properties like light and the ability to create more realistic renderings with a new high-quality ray-tracer. Video professionals have the ability to turn any 3D object into a video display zone and can animate 3D objects and properties with ease. In addition, the core motion graphics editing has been improved with more efficient single-key shortcuts."
