I THINK Xcode means that they are bringing MacBook Pro apps over like Final Cut Pro and logic. I THINK.
Xcode and the Pro Apps FCP and Logic are not related at all and very different in their target audiences. One coming doesn’t mean the others are as well.
The future of the Pro apps cannot be guaranteed by anyone either, as the example of Aperture has sadly demonstrated. Once Apple loses interest in the topic and falls behind, that might be it for the product.
