That’s right, Microsoft has finally let the cat out of the bag on all the Zune HD info we’ve been craving, and we’ve got the full scoop for you right here. First and foremost, the Zune HD goes on sale on September 15, and will be available in 16GB and 32GB size capacities. The two units are identical in every way, other than storage capacity, so let’s run down some of those specs.

• Built-in HD Radio receiver
• 720p HD video output through a premium dock (costs extra)
• OLED touchscreen: 3-3-inches, 16:9, scratch-resistant glass
• Built-in 802.11b/g Wi-Fi
• Web browser
• NVIDIA Tegra low-power HD processor

The Onyx Black 16GB Zune HD will sell for $219.99, while the Platinum Silver 32GB model will sell for $290 - compare that to the $299 and $399 prices for the 16GB and 32GB iPod touch, respectively. If you aren’t down with black or platinum, wait until September 15, and you’ll be able to pick from five other colors through the Zune Originals program. We’ve got even more specs for you after the cut, but if you’ve heard all you needed to hear and want to pre-order the device immediately, head on over to Amazon where you can find the 32GB Silver Zune HD, as well as the 16GB Black model.
