PocketCenter.de is completely on the forefront when it comes to CeBIT pictures. They managed to snag their hands on a HTC Universal (MDA IV) and held it up to a HTC Blue Angel for size comparison.
It's a little bigger, but not bad -- I certainly wouldn't mind if someone were to hand it to me.
You can see more pictures of new Pocket PC Phones (including a side comparison shot of the Universal)
in this gallery. Some other peripherals, including a very small SDIO WiFi card, are
in this gallery, and finally, a preview of the Acer n20 is
available here. Man, I wish I were at CeBIT.
