It won't - when an ObservableList is used we will maintain the current 
behavior of not retaining the original, unsorted state. For people who 
want to support returning to an unsorted state but otherwise have 
functionality like that of a normal ObservableList, they will do 
something like this:

SortedList sortedList = new SortedList(SortedList.UNSORTED); // where 
SortedList.UNSORTED is a special Comparator
TableView tableview = new TableView(sortedList);

I've not been closely involved in these discussions, so I'll leave that 
to Richard and / or Martin to answer.
