It's not like they threatened anyone. They likely went to the organizers and said "We'd like to make a really cool announcement at your event but we'd need most of your presentation and sponsorship space to do it." SuperMeet said sure, Apple paid, and here we are. It's not like the other sponsors didn't get their money back (I'm assuming.)
The other presenters just had to toss months of planning out the window and scramble to reschedule events w/less than a weeks notice during the industry's biggest annual convention. Hopefully the members of the audience that signed up to see the original line-up will be able to make it to all the reschedule events and, on top of that, everyone going to the SuperMeet has now paid money for tickets to what is nothing more than an Apple PR event.
Dick move by Apple but all will be forgiven as long as they release the holy grail of editing on Tuesday. If they preview 'iMovie Pro' lord help them...
He is asked if he will update his editing studio's workflow to the new Final Cut, and he basically danced around the question, pleaded the 5th, and made it pretty clear that he is holding back some reservations about how the industry will adapt to the changes.
To be fair to Mark (the head of Post at Bunim/Murray) there really isn't anything he could say due to the NDA. Just because what he saw of the new FCP might not lead him to believe it would work in Bunim/Murray's current workflow doesn't mean it might not be awesome for someone else's work flow. It was a tough spot for Mark to be in and I'm not exactly sure why he even kicked off the meeting with "I was there, but don't ask me about it because I'm under NDA". He could've never even have brought it up and it wouldn't have altered the course of the conversation at all.
