Some internal documents have just surfaced from Sprint, revealing their line up of HTC devices for this year. The HTC Diamond and HCT Raphael are plainly shown as being replacements for the Touch (diamond) and Mogul (Raphael). The HTC Raphael will feature TouchFlo technology, EVDO, a full QWERTY keyboard, 3MP camera, Bluetooth 2.0, and is slated to launch in Q4.
The HTC Diamond, which will be replacing the Sprint's Touch will most likely feature all the same specs as the Raphael, but without the QWERTY keyboard. I'd imagine that this information is not what was planned on being released at HTC's May 6 press event in London, which only means there's still more news to come.
