This Vid (GT Eiger Rally already posted)
http://www.youtube.com/watch?v=9XlZU7-MWEE
is not by RDK - it's by another user (GT5Launchstuff on youtube I think) who also posted the video showing a Standard edition copy of GT5 being opened.
So, the dust not sticking to the rally car is a problem because it is not RDK or Tekken's copy of the game, but a seeming new one.
Personally, I think the videos by GT5Launchstuff are probably final version. RDK and Tekken seem to have CE versions but no associated stuff (the Apex manual for example) so it may be they got copies which for whatever reason were removed from real CE versions - could be bad print runs, wrong versions or whatever.
However, the lack of dust-stick in this latest Eiger Rally vid is problematic. It is the Arcade mode, and according to the games manual, in Arcade mode you can have 2 player (split screen?) races - in which case graphics and damage may be toned down in that mode.
Rotor.
