“Unless Microsoft's playing a nasty trick on its loyal fanbase, the latest Zune newsletter confirms a feature-laden software update, very likely what we've been calling Zune 4.0, is due out on Tuesday, September 15th, the same day as Zune HD takes its place among its fading peers.”
I haven't actually gotten my newsletter yet so I'll have to take Engadget's word that that it has a real newsletter. In some of the least surprising news I've heard in a while, its essentially confirmed now that the next iteration of the Zune software will launch with the Zune HD on the 15th.
I'm definitely looking forward to many of the reported features, especially HD movie content. I keep dreaming of the day that I no longer buy my content on media and get it all digitally and I hope that this moves me one step closer!
