It's a pretty radical move but a smart one, with the success of the App Store for iPad and iPhone, iTunes for Music, TV shows and Movies, what they're probably going to do with all the Pro Apps is to have them released individually in the App Store and then bring out a different AU component and plugin store for the different apps.

They'll get a lot more users because FCPX and LPX will be $299 and then you pay for what you use and on top of that they make a 30% on everyones AU components and FCP plugins, the plugins will probably be a lot more interchangeable between the two apps.

I'd love to have a kick ass EQ or vocal Desser in FCP but the GUI for AU components are terrible
