For some reason the link for part II of the video (where Kitase confirm they have to cut content from PS3 due the 360 version) was removed and redirect always to a Quake video.
But I found this copy...
@zero129 you can be happy now.
Edit - Oh God!!! Ninjas removed this copy too... the video didn't exist more in the web... I will try more underground searches.
Edit 2: Finally the video...
