No one really knows whether HTC's May 6 gathering will usher in the age of Android (our guess is still "no"), but let's look a little beyond that, shall we? We've just laid eyes on a handful of documents detailing HTC's efforts to ready the Diamond and Raphael models -- already known to be valid HTC codenames -- for Sprint later this year, and things are definitely looking up in the post-Touch world. The Diamond turns out to be the successor to that very device, lacking a physical keyboard and relying almost exclusively on a large, glossy touchscreen for user input; the Raphael meanwhile (pictured) features a full QWERTY deal and is destined to replace the Mogul. The paperwork's pretty blurry, but it appears that both Windows Mobile devices will feature WiFi, 3 megapixel cameras, and -- get this -- VGA displays (yup, that's 640 x 480 resolution). Goodness! The Raphael is currently lined up to be the first out of the gate, hitting the streets in September if everything goes well, with the Diamond following on in November. Surprised that these devices are CDMA-based and Sprint bound? Us too, we admit -- but we'd be shocked if there weren't GSM twins of both of these hotties getting cooked in the lab at the same time.
