Update to Beovisions to be able to use Level or Balance as speakers for video related content. Not sure if its' going to happen but might be more in the works than to have a Stage Mk2 which could connect to these speakers.
However Stage is a good volume driver for B&O, so they will be extending this kind of product range in my opinion, so an more expensive stage Mk2 which allows more speakers would be an logical option. But they can't leave current B&O buyers behind. So your $2k stage can connect to a balance speaker and your $20k harmony can't do it. That would be a route B&O is not going to take in my opinion. Or make all connections avalaible no matter what product it is. That would be the way to go.
