Probably no one really knows but its worth a shot to ask?

What we know is that it is Bluetooh v3.0.

My question is that, i will have a bluetooth mouse, keyboard, speaker phone, phone headset, etc, connected to my PC. How will Win8 deal with usb enumeration, or how will it deal with dual usb enumeration.

My main concern is using bluetooth devices with softphone applications(skype,lync etc).
How will Win8 respond to having two or more audio devices connected, i.e. a Speaker phone and a Headset.
How will it choose between the two devices?

Today, as far as audio devices go, I will need a usb bluetooth dongle for each device. So i would have 1 dongle for my headset, 1 for my speaker phone, 1 for a wireless mic, and etc... you can see how one can use up their usb ports fast. Of course you can unplug and plug each one as needed but wouldnt that be a hassle when dealing with 2 or more devices.

How will Win8 handle this...

As far as ideas goes, I would hope that there will be some type of UI where it displays the available bluetooh devices. If i am on a call, and say my headset dies, it should automatically connect to the next device (some type of hierarchy of BT devices). And say im using a speaker phone, but now i power on my headset, the UI should notify that i connected a headset and asks if i want to use it for phone call. Maybe even connect to it automatically. Thats a general idea of what i hope Win8 is capable of.

That might be a provision of the BT driver/support software, not Win8 itself.
