Just watched a webinar preview and learned that Final Cut Pro X is not based on Quicktime, will not support log and capture as tape does not have metadata. It supports multiple sequences, similar to SE sub-projects. It has clip markers. It allows for clip connection and the timeline has no hard fixed tracks. Storyboards are available within complex clips. Sequence duration adjustments can be done with speed ramps. Subframe timeline accuracy is used for audio clips. Built in colour correction and automated colour balancing upon intake. Titling with animation.
So far it seems that SpeedEdit does most of this, except for the timeline accuracy, metadata organization and 64bit. FCPX does look nice though ... if you have a Mac. Apple expects to sell a few million copies in the first year and it is meant to use along with FCP7 and not replace it.
Newtek has obviously been ahead of developing some of these ideas. Apple is putting it's resources to marketing and expanding on the direction. Newtek could ride this wave for those on a Windows computer if they focus their marketing team on SpeedEdit.
