Panasonic DMC-GH2
It was back at Photokina 2008 when Panasonic first introduced Micro Four Thirds, so it made total sense for them to use this event do drop their newest MFT body. New features like 3D compatibility (when using the interchangeable 12.5mm f/12 3D lens) and the "world's fastest autofocus" make it a step ahead for the format as a whole. Of course, Panasonic has also picked up a lot more competition in this arena since then, most of which was on the show floor this week.
