Hmm... "exceptions" to USB connections for active accessories. That leaves WiFi (given) and possibly Bluetooth for connection. My hopes are slightly up.
I already own a couple of bluetooth enabled speaker docks. I don't know of any speaker dock using WiFi. It would be great if this ZuneHD or the next one would have bluetooth. I rank all my players with bluetooth at least one notch above any that don't. That kept the Touch off my top tier, but Apple is fixing that shortcoming with the 3.0 update that will be here any day now.
