While the company hasn't yet announced an official release date for the product, there will be a public beta made available. Apparently Adobe wants to get some feedback from the end-user community before putting the spit and polish on the released product. Those interested in participating in the public beta can do so by signing up at Adobe Labs. You'll be notified when the beta is available, which is said to be sometime this winter.
Not that this will be a concern to many, but in order to use many of the many of the DSP algorithms and processes present in Audition, you'll need a 64-bit processor.
