The Zune website now has the message about Zune being discontinued again, and the Microsoft Store now shows the device as out of stock. In addition, the latest official Windows Phone Radio podcast (episode 45) includes confirmation that the Zune HD is no more (around 12:40 in). The same rules apply as before (support for the Zune is still around, just that Microsoft won’t be producing anymore units to sell, so if you see one in the stores, grab it before it’s extinct!).
Looks like it’s the final nail in the coffin for Zune players – unless of course, Microsoft changes its mind yet again.
