As we noted, Zune services have been taken offline as Microsoft prepares for the launch of Zune 4.0 software, improved Zune marketplace and services and of course the Zune HD. No word on when they’ll be back online, but we’re guessing midnight.

Of course, expect heavy action tomorrow with everyone downloading the new Zune 4.0 software and the release of the Zune HD.

Exciting week upcoming with the release of Zune HD on Tuesday, September 15th. This day will also mark the release of Zune 4.0 software and zune.net updates. Microsoft informs us that Zune Marketplace, Zune.net and Zune Social will be taken offline around 11:oo PDT.

Tuesday will bring new services, new software and the Zune HD. While you’re waiting, it’s likely we’ll start to see reviews from the major tech outlets. Of course, you can also sign up for our Zune HD forums and discuss the release.
