First up is the successor for the HTC Hero, the Legend. This is the phone everyone was talking about last week, so there's definitely an air of excitement around this one. Running Android 2.1, you're looking at a 3.2-inch AMOLED HVGA and an optical, joystick-style trackball, which is surrounded by a clickable button.
Right now, details are scant. The phone itself looks like most of the other HTC phone we've seen over the last year or so, but with one very big difference. The Legend is fashioned from a single piece of aluminum, a la the new line of MacBook Pros. HTC even goes as far as to refer to it as a unibody HTC. The Legend will be available in Europe through Vodafone, starting in April. Asia and 'other parts of the world' should see it in 'early Q2.'
Next up is the Desire. A little bigger than the Legend, the Desire's 3.7 inch AMOLED WVGA is powered by a 1GHz Snapdragon processor and is Adobe Flash 10.1 ready. It uses the same joystick/trackball as the Legend and is basically the Nexus One but without Google. It also boasts HTC's Sense UI, which is not present on the Nexus One. HTC Desire will be broadly available to customers across major European and Asian markets in early Q2 and exclusively available in Australia through Telstra.
Lastly, you've got the HTC HD Mini, the only Windows Mobile phone of the bunch. Running WinMo 6.5.3, the device is a stripped down version of the HD2. The HD Mini is to the HD2 as the Pixi is to the Pre. It packs a 3.2-inch HVGA display and on tops of Windows Mobile, boasts HTC's Sense UI. Details on this little smartphone are pretty thin on the ground, but it's set for a European and Asian release in April so more details should come about before then.
