Just how good will the HTC Touch Diamond (Diamond), HTC Touch Pro (Raphael) and HTC Touch Dual Pro (Titanium) prove to be?

Damn good, that’s how good.

HTC is really pulling out all the stops with their upcoming upgraded handsets. HTC’s still unannounced Diamond, Raphael, and Titanium handsets are going to hit the scene to much fanfare and we’re hoping to see at least one of these devices on May 6th.

Packed full of features and oozing sexiness, the new HTC Touch devices are poised to give the smartphone market some serious competition.

So, just how good will the handsets be? Let’s find out.

[Update]
Check out the new pics of the HTC Touch Diamond after the break!

HTC Touch Pro
Otherwise known as the HTC Raphael, the HTC Touch Pro will apparently take HTC’s sliding QWERTY keyboard form-factor to new levels. The 2.8-inch glossy VGA touchscreen display is the main aesthetic draw on the HTC Touch Pro, but that doesn’t mean the goodies end there. Here’s the feature-set:

• Windows Mobile 6.1 Professional
• 256MB ROM / 128MB RAM
• Qualcomm (NSDQ: QCOM) MSM 7201A @ 528MHz
• 7.2MB HSDPA / HSUPA (rev A EVDO for CDMA versions)
• 2.8″ VGA (480×640) touchscreen display
• QWERTY keyboard
• TV out
• Bluetooth 2.0 + EDR
• WiFi
• Orientation sensor
• FM Radio
• eGPS
• 3.1MP Camera with flash
• Front-facing camera
• microSDHC card slot
• 900mAh battery
• Enhanced TouchFlo

To top it all off, the HTC Touch Diamond is expected to hit the scene with eGPS – a technology introduced by UK’s CSR in February. While GPS is good and all, the low-power receivers on handsets can take a long time to lock onto a GPS satellite. So, aGPS was introduced to shorten satellite lock-on times by supplementing the GPS positional data with network positional data. Now, the newest network assisted GPS technology to hit the market is eGPS and the HTC Touch Diamond will be making good use of the faster, lower-power, and more accurate GPS positioning technology. eGPS allows the device to get a GPS-fix in under 4 seconds, even while indoors, with an accuracy of 10 meters. Power drain is equivalent to less than 1 second of voice calls and the tech even works while the device is powered down.

HTC Touch Diamond
Known internally by its codename “Diamond,” will apparently be the thinner successor to the HTC Touch. And, with dimensions of 99×51x10.7mm, it shaves a handful of millimeters off its predecessor’s girth (102×60.96×15.24mm). But, it doesn’t stop there. The HTC Touch Diamond sports the same specs as its bigger brother, the Raphael, like the beautifully large (2.8 inches) and glossy VGA touchscreen display and eGPS. But, it forgoes QWERTY keyboard and TV-out in favor of 4GB of internal storage – allowing the Windows Mobile Professional smartphone to hold its own as a media-centric device.

• Windows Mobile 6.1 Professional
• 256MB ROM / 128MB RAM
• Qualcomm MSM 7201A @ 528MHz
• 7.2MB HSDPA / HSUPA (rev A EVDO for CDMA versions)
• 2.8″ VGA (480×640) touchscreen display
• Bluetooth 2.0 + EDR
• WiFi
• Orientation sensor
• FM Radio
• eGPS
• 3.1MP Camera with flash
• Front-facing camera
• microSDHC card slot
• 900mAh battery
• Enhanced TouchFlo

And, here are the newest pics of the HTC Touch Diamond! Enjoy.

HTC Touch Dual Pro
There’s also word that HTC is brewing up a successor to its HTC Touch Dual – known as the HTC Titanium (HTC Touch Dual Pro). The specs are the same as the HTC Touch Pro (Diamond) but the QWERTY keyboard is replaced with a more phone-number friendly keypad.

• Windows Mobile 6.1 Professional
• 256MB ROM / 128MB RAM
• Qualcomm MSM 7201A @ 528MHz
• 7.2MB HSDPA / HSUPA (rev A EVDO for CDMA versions)
• 2.8″ VGA (480×640) touchscreen display
• 12- or 20-key keypad
• TV out
• Bluetooth 2.0 + EDR
• WiFi
• Orientation sensor
• FM Radio
• eGPS
• 3.1MP Camera with flash
• Front-facing camera
• microSDHC card slot
• 900mAh battery
• Enhanced TouchFlo

We can’t wait to get our hands on the new pair of HTC Touch devices. If the spec-sheets are on-point, and the touchscreens prove to be not too “squishy,” we can expect to see a seriously tempting offering from HTC. Have you started searching the couch and under the car seat for loose change yet? These puppies aren’t going to be cheap!

I see a new HTC Touch in my future…
