All that is needed for G series is...
Quality tele lenses and better sports shooting ability. The coming 150mm f2.8 OIS is a start. A 1.4X and 2X TC would be helpful. Also need would be 200mm f2.8 OIS and 300mm f4 OIS. I am in the u43rds system for smaller high quality lenses and small overall system.
As far as a FF line, I would only be interested in Olympus doing this with their in-camera IS.
