From the looks of the graphics in the teaser video, it does look like it's referencing Sony Sound Forge. Sony (and Sonic Foundry before it) always uses a red icon to identify Sound Forge. But as a video editor, I would LOVE to see a Mac version of Sony Vegas (which has a blue icon). Vegas started out as an audio-only editor, and they added video editing features on top of it. This resulted in an audio-centric workflow when working with video, and editing multi-track audio into a video project was simply a breeze. I often exported AAF files from other editing software and opened them in Vegas simply to sweeten the audio. The extra step was worth it considering how elegantly Vegas edited audio. And I know of a lot of musicians who use Vegas exclusively to record multi-track audio. Hopefully Sony saw the gap left open by the underwhelming FCPX and is thinking about porting Vegas to the Mac as well.
