From a Japanese website, we have photos of the 3 announced Panasonic Micro Four Thirds lenses on their way for 2010:
Panasonic Lumix 8mm f/3.5 fisheye
Panasonic Lumix 14mm f/2.8 – I would have preferred an 11 or 12mm instead.
Panasonic Lumix 100-300mm f/4-5.6 OIS (that’s a very compact 200-600mm telephoto reach in 35mm terms!)
see the website here.
