We can give you a translation of the review high-lights:
– The autofocus is very fast (and faster than on the Panasonic GH1). Even in extreme bright or dark situations! The say this camera allows a “new dimention of autofus speed, not comparable with the other Panasonic models!”
– They tested the AF-speed with many Panasonic lenses and the AF speed improves on all lenses!
– The AF is faster than the Canon EOS 5D Mark II autofocus!
– They like the Multi-aspect Bracketing. The GH2 can take 4 continous shots in 16:9 3:2 4:3 1:1!
– Even if the firmware was not in final stage the GH2 has better sharpness, dynamic range and HIGH-ISO than the GH1. They see an 1 stop improvement compared to the GH1.
They say the GH2 is not a revolution but a very concrete evolution of the GH1.
