Not yet official announced, Jason Langridge from Microsoft UK spotted the HTC Kaiser on the device bar at Microsoft's MEDC Europe 2007 which is currently happening in Berlin (Germany).
The HTC Kaiser will be the follower of the HTC Hermes (aka HTC TyTN) and sporting Windows Mobile 6 Professional, 3G/HSDPA, GPS and a 3.0 megapixel camera but whom I'm gone tell this since you all know the HTC Kaiser already.
But since it appeared first time publicly now, it cannot take to long anymore that we are going to hear an official announcement from HTC and its partners (most likely T-Mobile).

I've heard that we might hear more official information about the Kaiser mid next month already but that's a pure rumor yet. In any case - stay tuned for more and for now - head over to Jason Langridge's blog for more information.
