10x optical zoom for 4/3 Olympus (28-280)

I don't read this group too often, so forgive me if this is common knowledge. I just discovered a fairly recent Olympus patent the other day for a 14-140 zoom for the new 4/3 format. Aperture is ~ f/3.5 - f/4.5, 35mm equivalent is approx. 28-280mm, and it appears to be a legitimate "ED" design with fluor crowns located where they might actually do some good. The patent number is U.S. 6,483,648.
