The new OMD EM5II ?
#10
Sensor shift technologies have been around for a while.  In essence, for perfect results it requires a static subject.  The lens' aberrations turn a dot into a blur disk (the airy disk), the sensor shift moves the sensor around so it independently samples multiple points of the airy disk.  This allows it to roughly identify what the original point should have been and recover details that fell between photosites.  The result is an image of the same pixel count, but much higher per-pixel detail.  Of course one can digitally enlarge the image to a higher resolution and get similar per-pixel detail, but in sensor noise limited situations (i.e high ISO) you will not see much better detail due to the noise.
