Rollo,
Are you taking about the pro video suite, which contains Audition 2.0 -- the audio editing program?
If so, what is your need with Audition? I ask because Adobe is about to, or may already have, separated Audition out from the suite and is now including a stripped-down audio editor called SoundBooth, which is generally more appropriate to video production than Audition.
Audition will once again be a stand-alone audio editor aimed at the higher-end amateur/pro recording engineer market. The next phase of that development is just starting, so it will be a while before Audition gets a facelift. I can't say any more than that as I'm under an NDA. What I've disclosed here is been publicly announced.
Also, if you don't know, Audition is the former CoolEdit Pro 2.1 which Adobe bought from Syntrillium a few years back. They did a minor facelift (essentially to Adobe brand it) and released CEP as Audition 1.0. Then they added more capability but kept the same basic interface, added VST plug-in capability, and called it Audition 1.5. Then they completely changed the user interface, made it much more complex, integrated it into the pro video production suite, and that was 2.0. FYI.
