Looks like the adapter a lot of us have been waiting for is finally available for order, the Metabones Canon EF Lens to Micro Four Thirds Speed Booster:

$599 is a bit steep, but I guess you have to pay for the extra electronics needed to control the aperture with your camera.
Personally I have already ordered mine, and am really looking forward to using it with my remaining Canon lenses, particularly the Zeiss Makro-Planar 100mm f/2 and Sigma 85mm f/1.4.
