cs4e also has some 3d/anim features that were not included in APS 5.
however, it's true - no P4 renderer in P8.  there have been some complaints about the new directory structure, but these things take time.  I thought there was a kind of mini-manual in the DVD case but apparently not now.  if daz wouldn't buy P6 from e-f, if SM couldn't sell P7 to autodesk, then there's no chance adobe will buy P9.  but we shall see.
