I want to know as well. I bought DV matte blast and it is pretty good, but I would rather have a nice keyer in FCP. I saw the new adobe premier has a decent one. If I could key in FCP, that would save me a lot of headache in roundtripping.
When you play with the software, see how well you can pull a key on a “not so good” clip and see how it stands up.
We are foaming at the mouth with anticipation!
