If by controller you mean the touchpad, I don't think we'll see that any time soon in a f30. The changes coming in November seem to be mostly software with some faster hardware.
Personally, I think the current system is pretty decent, and from what I can see the new one doesn't appear to be a huge leap forward. The interface looks slightly slicker, there's some nice new features like dragon drive and weather. Overall though, I don't see much that isn't already there in the current system. If you're unsure, head down to your dealer and have a good play with the current system. Its a long wait till January.
