Well, according to Davis DVD you'll only have to wait until August, when Lion's Gate will be putting it back on the shelves ...
"Lions Gate Home Entertainment plans on re-releasing Takashi Miike's incredible film Audition on DVD sometime this August. Previously released through Ventura Entertainment, Audition will include a new introduction and on-camera interview with Miike, select scene commentary with Miike, a Q&A at the American Cinematheque, a Tour of the Egyptian Theatre, an interview with author Ryu Murakami, a photo gallery, trailers and more."
