Olympus patent discloses how you can use multishot to reduce noise.

We know the E-M5II will have sensor shift function to create high resolution images. A similar multishot technique could be used to reduce noise as a new Olympus patent explaines. Two (or more) images shot at different exposures can be used to create one single image with very low noise. In that case there is no sensor shift in action but just two same images shot at different exposures just like you do when shooting HDR.

And in a second patent Olympus also explains how to get rid of blurred images. That yes could be used in conjunction with the sensor shift mechanism as this is likely to create some blurred images when objects are moving.
