Yes, it’s a major improvement. Yes I will buy upgrades for all three of my licenses of FCP. Color alone is worth the price. BUT –
The problem is that all these separate apps have to work together the same way from one version to the next. I’ve been burned several times by trying to migrate an old project from version 4.5 to version 5.x only to have FCP deal with various elements (Motion elements, Soundtrack projects, etc.) in a different way, causing the project to go haywire and requiring a lot of work to get things back in order. This is the main problem of not having some of these features built-in. If FCP gets an update and the other “integrated” apps do not, keep a lookout for problems like this.
