Sweet new iRiver watch / PMP

I just was perusing Gizmodo, when I encountered this neat gizmo. From the article, it sounds like this device will support wireless headphones!  That would be incredible!  A watch-like PMP that wirelessly streams music over bluetooth.  Apparently they would have to leap some technical hurdles for this to work well, however, as in my experience bluetooth doesn't have the bandwidth to deliver high fidelity stereo audio.
