Think the Stage is going to get replaced or updated soon? Any idea what new features or capabilities it might have?
What makes you think that?
The Stage was also part of the recent price hike.
There have been discussions about the likeliness of a Stage "Plus" launch (based on Mozart and capable of accepting other speakers as surround/satellites channels), but given the shortage, the price it would need to have, etc, it's pretty much excluded at least short-term.
