Olympus patents a 300-500mm f/2.8-4.0 lens: Another supertelephoto zoom for MFT shooters?

Thanks to the generous two times crop factor of Micro Four Thirds cameras, you can achieve a lot of telephoto reach in a relatively small form factor. Take the Olympus 300mm f/4 IS Pro ED M.Zuiko lens, for example, which is just under 9 inches long despite offering a 600mm-equivalent focal length.
4/3 Rumors has dug up a patent filed by Olympus which shows two possible MFT telephoto zoom lenses. The first optic is a 300-500mm f/2.8-4.0 and the second is a 200-300mm f/2.8-4.0. These would provide equivalent focal lengths of 600-1000mm and 400-600mm respectively, both very appealing options for wildlife and sports photographers.
The 200-300mm patent shows a length almost identical to the 300mm f/4 Olympus lens whereas the 300-500mm lens would be just over 13 inches in length, still a very reasonable physical size for its equivalent focal length and aperture. For more information on the lens designs, see the full patent information here.
As is the case with all patent filings, they aren't necessarily indicative of a company's immediate plans to release a product. I'm sure Micro Four Thirds shooters would be thrilled if the 300-500mm lens in particular did come to market as it would be the longest MFT glass available, besting the already impressive Panasonic 100-400mm f/4-6.3 ASPH Power OIS Leica DG in both maximum focal length and maximum aperture across the range.
This patent filing comes only shortly after Canon patented a potential 40-800mm lens for full frame cameras. If these patents come to fruition, there'll be no shortage of long zoom lenses.
