Someone has posted a video on Youtube that's causing some debate. It looks like Adobe Audition running on a Mac, which if true, and it is eventually released, would be very interesting. I think a lot of users may abandon Pro-Tools if the price point is low enough.
Of course if it's not ever officially released and isn't VMWare or something, I suspect that we'll start seeing many beta versions of this running in studios like some other bits of software that were never officially released and are used professionally even though they're pretty buggy. You know who I'm talking about.
