It is good to see that MIDI controllers have been added to VV5, but it still seems as though the MIDI features are half-assed. It is essential to have full MIDI sequencing (like Acid, but actually good), rewire support and native VST support. With these features, Vegas would truly be the king of the A/V prosumer world.
The bottom line is that I don't want to use both Acid and Vegas. I want only to use Vegas. It is the only way to create really tight audio and video edits at the same time (No Mac program supports this as good as Vegas).
