Just to be fair to Rob, the firmware update didn't fix the most glaring problem - the lockup associated with jumping to the macro side.
Daniel's probably right about Marantz being able to get a new version if they want one. Some of the software features in the 3000, such as jump back/forward and multiple jumps, were actually engineered (or at least funded), by Marantz. Marantz long retained exclusive rights to these features. The fact that they've finally showed up in a Philips remote leads me to believe there is still some sort of relationship/colaboration going on.
