HTC's model naming convention has always been just a little tricky to commit to memory, and with this latest batch, it certainly ain't getting any easier. A couple of these we've heard about before -- namely the Nike, Kaiser, and Shangri-La -- but the rest are brand new to us and very exciting. First up, the S640 "Iris" is a CDMA rendition of the Excalibur and Cavalier, tossing in EV-DO rev. A and WiFi atop Windows Mobile 6 Standard. The "Vogue" is essentially a Touch (TouchFLO UI and all) with the same EV-DO rev. A guts as the Iris -- good news for Verizon and Sprint customers, we'd imagine. GSM users have reason to celebrate here too, though, in the form of the "Volans" and "Polaris." These two are upgrades to the Vox and Artemis, respectively, adding in much-needed 3G radios and faster processors. Finally, the P6550 "Sedna" appears to be some sort of industrial device with support for a credit card reader -- though with a 3 megapixel cam and 3G data, we wouldn't mind having one ourselves. Release dates are up in the air on most of these, but our money is on late '07.

Update: Crikey, the Shangri-La's slide reveals that the device -- HTC's entry into the UMPC fray -- runs both Vista and Windows Mobile 6. Sound vaguely familiar? [Thanks, Kevin]
