This might be a pretty good indicator of an updated lens. Kenmore Camera seems to have a close relationship with Panasonic and usually gets lenses in stock fast. They might of gotten advanced notice of a new lens? Hopefully it gets slightly improved optics and a size reduction similar to the 14-140 II.here you go,http://www.kenmorecamera.com/p-36823-panasonic-100-300mm-f4-56-2nd.aspx
Wonder if it is just one with accessories and one without. Don't know, rumors how we love rumors.
