A new disc is reportedly coming from Classic Media on September 5. No details yet; it's supposed to have the Japanese cut, so it's not clear if it will also include the U.S. version.

The Simitar discs tended to suffer from bad compression; the Classic Media disc that came out in '04 (I think) has the same transfer but better compression and authoring. So if you don't want to wait until September or don't care at all about the Japanese cut, I'd recommend the Classic Media disc. (This is the same one being referred to as the "Sony" version. Actually Sony is only the distributor.)
