HTC’s kicking the Windows Phone 7 era off in style today with no less than three new phones scheduled to debut on October 21 in Europe: the HD7, the 7 Mozart, and the 7 Trophy. Both the Mozart and Trophy offer a WVGA LCD screen, a 1GHz Qualcomm MSM8250 chipset, 576MB of RAM, 8GB of built-in storage, and 720p video recording. Where the 7 Mozart sets itself apart is in having an aluminum unibody construction wrapped around its 3.7-inch display, together with a more advanced 8 megapixel imager and a Xenon flash. The 7 Trophy makes do with an LED flash illuminating 5 megapixels’ worth photons, but it does also come with HTC’s promise to be the most aggressively priced WP7 handset from the company. It’ll be a Vodafone exclusive across the big red network’s global footprint, while the Mozart will be exclusive to Orange in the UK, France, Spain, and Switzerland, exclusive to Deutsche Telekom in Germany, and available on a choice of carriers elsewhere. No peep of an American release for either handset, however.

For the home crowd, Sprint is set to deliver a HTC 7 Pro with a QWERTY keyboard that slides out and tilts — you can see it pictured in the gallery below — at some point in the first half of 2011. It too goes with the same old 1GHz Snapdragon, 576MB of RAM, 5 megapixel cam plus 720p video, and WVGA display resolution (on a 3.6-inch screen), but it gets a bump in storage to 16GB.
