If you shoot 4/3 format cameras look for sales on OM Systems products.
OM Digital is in the process of re-branding all of the existing products from Olympus to OM Systems. Lenses will soon carry the OM System in lieu of Olympus. It seems Zuiko will remain the lens moniker which is nice 'cause OM Systemphile doesn't have the same ring as Zuikophile 
Camera bodies will wait for an upgrade ala the OM5. There are more upgrades on that camera than I thought at first glance but still it's an upgrade and not a "new" camera.
Differences between OM5 and EM5 mk III: OM5 is in the left column. As you can see there some substantial computational additions. The new processing engine is likely as big a change as any of the others. Image processors don't get the attention they deserve. Hoshizora AF refers to AI assisted focus.
