I've asked samsung and got this reply:-
Software updates are released in batches and release dates for them will vary by region. As they are often rolled out over the period of a quarter, it may be this long until you receive the update.
Have you enabled automatic updates? If enabled, this should ensure that you get the update as soon it becomes available; you can find this option by following these steps:
Applications>Settings>More>About Device>Software Update/Automatic Updates (Change to On). ^BC
So it looks like the long wait begins again
