The US Olympus store offers refurbished E-M5 cameras for $759 (Click here). That is he lowest price you can pay for an E-M5 with full guarantee. And in Germany the price for the E-M5 is now officially 899 Euro at Amazon Germany and Technikdirekt.
The GH3 is still out of Stock in US or in Stock only if you pay some huge extra $$$ via third party resellers at Amazon US (Click here). The story is completely different in Europe where the price even lowered down form the original 1199 Euro. You can find the body now for 1035 in Germany (see Idealo.de). Yep, Panasonic has still a problem with proper delivery in US
