I don't think it has actually been finished. While he's screened something called The Whole Bloody Affair at the New Beverly a couple times iirc it was actually just the original Cannes cut (and still includes the French subtitles from that showing), and did not have the new anime sequence he said the Whole Bloody Affair would include.
AH ok that makes sense. I thought it was already complete and that QT was withholding it for some bizarre reason.
