(FT4) New sensor to be ready for end 2014 early 2015 only.
I got this info by two trusted sources. The new GX7 will not feature an organic sensor and we can expect first camera using the new tech by end 2014 only (and probably shipment in 2015). And yes, the organic sensor tech can be combined with the Color Splitter technology from Panasonic!
This all sounds exciting but there is still a long way to go. Be happy with the old classic Bayer sensors for now :)
