After the leaked pictures of the Zune HD appeared on Saturday, more unconfirmed technical specifications of the device have now emerged. Microsoft's new portable media player is set to go neck-to-neck with Apple's iPod Touch, as the specifications of the Zune HD make it a viable contender.

The Zune HD is set to feature a multitouch (capacitive) OLED screen in a 16:9 aspect ratio and will have a TV out port on the side (apparently HDMI). Coming in 16 and 32GB versions, the device will also support wireless syncing to your computer. Some even speculate the PMP will support 3D Xbox games, if the Zune HD will actually use Nvidia's Tegra chipset.

The new details also mention a Web browser on the Zune HD, which in turn supports multitouch. No word on what kind of browser this will be, but let's hope it won't be anything similar to Internet Explorer on Windows Mobile. As previously reported, the Zune HD is set to launch this fall (probably September) with new details of international availability in Canada, the U.K, and France.

What is Microsoft cooking?

The tech blogosphere is also talking today about Zune-themed mobile phones. AdWeek reports that Microsoft is now taking bids for an ad campaign for a Zune mobile application dubbed Pink.

While some speculate that the Zune HD is likely to run on the long-overdue Windows Mobile 6.5 (expected in Q4, same as the Zune HD), it's more likely that WM phones would just share some services and feature with the new Zune.
