“Dear Final Cut Pro customers,
As you know, we’ve just released Final Cut Pro X. We’re really proud of it. It represents the future of what’s become the most important piece of software for professional video. There are features in it — like the magnetic timeline — that we think you’ll love, and that will help you work faster open up new creative possibilities.
However, in rebuilding Final Cut Pro as a 64-bit application from the ground up, we’ve had some tough decisions to make. That means some of the features you’ve grown to love aren’t there yet.
Final Cut Pro X is the future of video editing, and we recommend you upgrade to it as soon as possible. But if the feature you need isn’t there, we’d like you to know that we’re working hard to add in the key tools our professional customers know and love, and meanwhile we’re going to continue selling and supporting Final Cut Pro 7 until at least the end of 2012.
See? That’s really not so hard, is it?
