News about the launch date along with more details on the specs have been posted in the official press release. The important stuff: September 15th release; $220 / $290 for the 16GB and 32GB respectively; in store colors 16GB comes in black- 32GB in platinum; ZuneOriginals.net you will be able to get 5 different colors with 10 different engravings in any capacities; 33 hrs music / 8.5 hrs video.
All great news and some sweet looking specs, however, one thing this is really concerning: lack of DivX/XviD support. Windows 7 along with XBox 360 supports these file types right out of the box. The Zune HD features one of the most powerful mobile graphics processors to date, so it’s somewhat disheartening to see the lack of support for mainstream codec that is already supported on other Microsoft products. By contrast many of the other players such as the Samsung P3 or the Cowon S9 both playback DivX/XviD quite nicely.
If you are a DivX fan and are interested in the Zune HD I would encourage you to be vocal about this issue in the Zune HD forums and across the web. It is something that is possible to add in future firmware updates.
