Zune HD - Release date When?

So I'm a bigtime Zune fan.  My brothers and friends all pitched in about a year ago and got my a Zune 8GB for a bachelor party gift, and I've been hook ever since.  So when I heard the new Zune HD is on its way, I had to find out when I could get my hands on this new gem.

Problem is, tho, that nobody seems to know yet when it's coming out.

I've been searching around the web, trying to find at least some sort of supposed date of release, but to no avail yet.  Geeksmack.net has it at September 8th.  Engadget HD, if you search deep enough, has it around the same time as Windows 7 releases, which would put it around mid-October.  CNET Reviews simply uses the vague time period of "fall of 2009" as a release date.

So when is it?  Anybody have any ideas?  Post in the comments!!!
