Incredible, especially the 7/X incompatibility. Initially Apple stated that the incompatibility was due the the "new advanced architecture" used by FCP"ex", making it sound like it was a 64 bit architecture issue. Well, AVID and Adobe seemed to make that leap just fine. As Apple has made clarifying statements, it now seems to be due to their insistence on denying that "tracks" can or should exist.
Bottom line - I had an FCP wishlist that included native MXF support, 64 bit processing, updates or integration of DVD Studio Pro and Color functionality; not hard stuff. Instead, we get a bastard product that I'd compare to a radical new car design - sexy body if you can find the doors, 1000 hp engine governed to 90 hp and only one wheel (but third-party vendors will sell you new wheel mounts at an unspecified later date...)
