There was a reason why i did a purist version for ANH:R and that reason doesn't count for ROTJ:R. In fact i might run a competition sometime to see if anyone can figure out the real reason behind the purist edition.

I'll take a guess. The purist edition was actually only purist in the audio sense. All the major sound/dialog changes were reverted to their original versions. So either the purist was a prototype for the ANH AVCHD version's audio, or it was an attempt to please someone who complained heavily about the alteration of the original soundtrack.
