We knew HTC would make a splash with its new smartphones at MWC, but we're still a little taken about by the amount of new product appearing from the company today. That includes three new members of the Sense family - the HTC Desire S, HTC Wildfire S and HTC Incredible S. The 'S' presumably short for 'Sense'.Familiar names (at least, in the case of the first two smartphones) and as we mentioned above, all using the HTC Sense interface and with access to the Sense.com back-up service. 'HTC developed the HTC Sense experience to bring cutting-edge innovation to our customers in simple and natural ways that just make sense - this is what HTC Desire S, HTC Wildfire S and HTC Incredible S represent best,' said Peter Chou, CEO of HTC Corporation. 'These new phones offer an exhilarating mix of style, innovation and features that extend people’s mobile experience in ways that feel personal and completely original.'The HTC Desire S is a successor to the huge-selling HTC Desire and is apparently inspired by the HTC Legend’s aluminium design. Indeed, it's sculpted out of a single block of aluminum making it feel 'solid and natural' in your hand. Inside, you'll find Qualcomm’s new 1GHz Snapdragon MSM8255 processor, with dual front and back cameras (5-megapixel for the former), high-definition video recording and a 3.7-inch WVGA display and Android 2.4 for the operating system. Yes, the upgraded version of Gingerbread. HTC Wildfire S also builds on the success of the original, but still lives in the land of 'affordable'. It's also still small, just 10.13cm long and 5.94cm wide, but able to boast a 3.2-inch HVGA display. Features include a 5-megapixel camera with auto focus, expandable microSD memory, colour options including black, purple and white and a fully customisable home screen with your favorite apps, widgets and content and support for a variety of audio and video formats if you're a media fiend. Android 2.4 once again, which is impressive for a mid-range device.Finally, the HTC Incredible S combines what HTC describe as 'cutting-edge design with a premium mobile experience for those who dare to be different'. That means a contoured body that highlights the 4-inch WVGA Super LCD display, with an outlet for stereo surround sound, which is said to offer a 'vibrant cinematic experience to the palm of your hand'. HTC certainly don't believe in underselling a product.Features for the Incredible S include an unnamed 1GHz processor, 768MB RAM, 1.1GB of internal storage (plus microSD expansion), 8-megapixel camera with dual flash and HD (720p) video shooting, a front facing camera for video call functionality and easy sharing of videos, photos and music to a TV via DLNA technology. Android version 2.2 officially for this, but we suspect that might change before launch.Ok, that's the detail. Now the important part, when can you actually buy the HTC Desire S, HTC Wildfire S and HTC Incredible S? According to HTC, the phones will be 'broadly available' to customers across Europe during the second quarter of 2011, which is effectively early summer, with Orange and Vodafone already confirming that they will be ranging both the HTC Desire S and HTC Wildfire S.
