It's in the process of activating as well as an RS232 port on the RFX9400. Philips is really making a leap with their new range. I don't know though when they will be released. I am under the impression that both the TSU9400 and TSU9600 will support the ring. The issue is that there is really not much of a use if you don't use it for scrolling. Using it as a Volume Controller is a HUGE mistake. Someone might slide it all the way right and blow a pretty expensive system.
