From a Professional standpoint, the current version of FCPX is unusable on so many levels due to the absence of basic features that made FCP series the juggernaut it was until yesterday.
Here's my prediction of HOW Apple plans to distribute Plug-ins and Add-ons:
Apple is pushing towards a single, universal OS -- most likely a glorified iOS. And they're forcing FCPX users to upgrade to Lion so they have Appstore on their machines just to buy FCPX. Matter of fact, theyi're seeing more profit from Appstore/iTunes than their own computers! Ever since the success of the Appstore -- Apple/Jobs has been pushing to create products and services that will bring even more profit to the Appstore/iTunes business model.
Hence the release of the iPad and the development of iPad apps -- and the move to with OSX Lion.
The reason for this is so that Apple can take their flagship software like FCP --- and monetize all 3rd-party plug-ins and add-ons.
SO, once Apple has a consumer using FCPX, if they want Multi-cam or Import/Export features -- you will have to buy it as an add-on and sell all FCPX plug-ins and add-ons THROUGH THE APPSTORE.
Furthermore -- Apple will most likely force all 3rd-party developers to build plug-ins for FCPX as an APP -- and sell it THROUGH THE APPSTORE -- where Apple gets 30% commission -- stealing that money away from the developers, who in the past with FCP7, you were able to purchase directly from the developer.
SO -- FCPX isn't a revolution in editing....
FCPX is a revolution in MONETIZING FINAL CUT PRO PLUG-INS through the APPSTORE!
