I've just gone and read through the tweets from @fcpsupermeet, which describe the event. From comments like this (I pick this one as an example, loads of people are expressing the sentiment) I was expecting something really consumer-focussed, rather than:
Now, I'm not a video pro. I'll admit I'm a hobbyist: I was part of my university's film making society, and I've done various projects myself, but it's not my professional gig. But I can't see anything here that shows Apple moving away from the pro market. As far as I can tell they've done a really ambitious ground-up Cocoa rewrite of FCP, streamlining the workflow to make it quicker to use (no more render dialogs!), and at the same time building in loads of new tech like colour matching throughout.
Is the only thing people are bothered about the fact that they changed the UI? Because other than that, I just can't see what the complaints are about. We haven't heard any actual confirmed statements of features being removed, so why assume that any crucial ones have been? They'd have been nuts to switch away from a timeline-based system like iMovie did, and so of course they didn't do that. They rewrote everything from scratch to remove a bunch of legacy baggage (like the lack of multithreading, and the Carbon UI that prevented it going 64 bit), which is awesome, but I completely can't see any evidence of a change of focus.
