Add me as another vote for the desaturated version.
A request...any chance that you can include screenshots from the EE DVD and TE BD to compare against the existing EE BD and your regraded version? Since the idea is presumably to bring this fine film in its extended edition as close as possible to the colours in its theatrical, green-tintless counterpart as possible, I'd think that comparisons to the EE DVD and TE BD might be useful. Just a thought.
