Looks like somebody at O2 Germany put the wrong photo on the server. Instead of showing an enlarged photo of the soon to be released Xda star, O2 unveiled a so far unknown and unannounced Xda which looks like O2's version of the (also not yet announced) HTC Polaris. So it seems O2 Germany is working on a follower of its Xda orbit (aka HTC Artemis), a Windows Mobile 6 Professional smartphone which sports inbuilt GPS.
The new Xda is expected to feature Windows Mobile 6 Professional and GSM but also UMTS (most likely also HSDPA), Bluetooth and WiFi and the 3 megapixel camera seems to be confirmed now as well as the UMTS-typical front facing camera for video telephony (which confirms UMTS somehow):

Furthermore, because the device don't have softkeys but a quite flat screen instead, it seems to be confirmed that the smartphone also features HTC's new TouchFLO technology.

It's neither yet confirmed, if O2 Germany will launch the smartphone above or not (or if it was a pure mistake) nor what the name could be but if the device is O2's version of the HTC Polaris, it's another interesting looking Xda which follows the previously released Xda orbit design.
