It looks like some information has leaked about two upcoming Windows Mobile CDMA HTC phones coming to Sprint! They are code named Diamond (HTC Touch Diamond) and Raphael (HTC Touch Pro).

I think we can count on official news/information from HTC's UK May 6th new devices introduction party.

For now here's what we can gather from the leaked photos, and information from reliable sources. It's unclear if all of these features will be in the released version, or if some will be disabled (such as GPS was in the Titan initially). It seems likely the devices will debut on GSM before appearing on Sprint. Sprint is slating Q3 for the Diamond and Q4 for the Raphael. It seems likely that the Diamond could even hit before end of Q2 on GSM in Europe, with the Raphael to follow in Q3.

eGPS?

Bleeding edge stuff recently announced by UK company CSR in February. Basically it’s like aGPS but better (Qualcomm's upcoming gpsOneXTRA will be a competitor).

A typical eGPS push-to-fix will be available in less than 4 seconds, accurate to within 10 meters and require the equivalent power of less than 1 second of handset talk time.

It works indoors, when the device is powered down, uses less battery, acquires the sat signal faster and works globally.

How do the sizes compare to other HTC devices?

HTC Raphael (HTC Touch Pro) - 99x51x17mm
HTC Diamond (HTC Touch Diamond) - 99x51x10.7mm
HTC Vogue (Sprint Touch) - 102x60.96x15.24mm (4.0" x 2.4" x 0.6")
HTC Titan (Mogul) - 109.22x58.42x17.78mm (4.3" H x 2.3" W x 0.7" D)

Other info:

I think 7200A chipset is GSM only, there's some evidence that suggests the CDMA version will be based off the 7500A.

There is also information out there for model code named the "HTC Titanium" (HTC Touch Dual Pro). It's the updated version of the current Touch Dual. The Titanium/Touch Dual Pro is speculated to have that current slider dial pad but otherwise keeps the Touch Pro's specs. No information available if this model will be available for Sprint.
