Why is the EM5 so much more popular than the GH3?

I think Panasonic and Olympus have created the perfect pair of camera. On one hand they have the EM5 with its small size and incredible IS. Then we also have the GH3 with its extensive amount of controls and extra features along with its incredible video.

I guess the bottom line is that Panasonic and Olympus are not going anywhere. They may not be selling their cameras as well as Sony but that is not because of low demand.
