Seems that the previously rumored Ricoh GXR will be coming in December. It'll be smaller than even the slimmest micro four thirds out now and feature a system that'll make it the first to allow both interchangeable lenses and sensors.

The GXR body will go for about $700, the macro lens and sensor for about $1,000, and the zoom lens and sensor for about $500. If the system works as well as the video implies, we might have some rather fantastic cameras ahead of us.
