I don't expect it'll be forked more than Android has been before. They'll have added special things to it, but it'll still be based on Android and when it comes time for Android 2.4 or 3.1, they'll be porting their stuff to it instead of continuing with their fork of 2.3. They aren't the first to add special interfaces or change things that you'd normally assume were standard for the OS. And they won't be the last.
