Great news - other than I hope there is full feature parity, and of course that these apps get updates.
Final Cut Pro is simply not compatible with the macOS version which is completely ridiculous. Even if there has to be a watered down "iPad Project", you should be able to open the same library/project across platforms.
The same thing happened for years with iWork on the iPad.
Apple owns all the tech here. They want developers to do this but don't hold themselves to the same standards.
