Any rumors on the horizon about an m43 lens longer than 400mm?

Thanks Brandon, SHood and drj3 for the explanations!
I'd heard of Nikon's use of Fresnel lenses to create smaller telephoto lenses but DO was new to me.  The only other uses of Fresnel lenses that I'm familiar with are in overhead projectors and lighthouses!
