I know I'm not saying anything new since this was reported at BD and Fangoria amongst a bunch of other places, but this is new to me. SHOUT! Factory will be debuting Takashi Miike's Audition onto a 2-Disc Collector's Edition Blu-ray this October 6th. Specs include a new HD transfer from the internegative (I believe that's once removed from the negative), new stereo audio track, commentary from Miike and screenwriter Daisuke Tengan, Miike video introduction, over 90 minutes of new cast interviews, trailers, and linear notes by Tom Mes.
I have three DVD editions of this; the first U.S. DVD from Chimera, the second from Lionsgate, and the U.K. disc from Tartan. The last is generally considered the best transfer of the film. The Chimera is non-anamorphically enhanced and while the Lionsgate is--it's an artifact-riddled interlaced transfer. So hopefully this SHOUT! Blu-ray will present the definitive transfer on home video...at least for now.
