Anime News Network posted a link that tells us while Tarintino was doing promotional work for Inglorious Basterds that Once the Promotional tour for his new movie was over he would sit down and review the anime sequence that was done for the Kill Bill movie. Tarintino claimed that a very large chunk of the anime sequence was cut from the origional film becasue he felt that it was a wise move to do at the time. This doesn't even count the new footage that Production IG had just recently finished this year for the movie.
Aparently a long segment of Orin's vengance tale will be added to the Whole Bloody Affair. If Tarintino does keep this promise we could see The uncut Whole Bloody Affair come out by christmas or early next year. This is pure speculation on my part but at least this is what my instincts are telling me.
