According to the latest BCNRranking data Panasonic only holds 2.8% of the Full Frame market share in Japan. Eben less for Sigma but they only have the FP that makes their sales. I guess Panasonic expected to have a larger share by now with the launch of their excellent S5.

Nokishita has leaked the main specifications of the upcoming lens:

The specifications of Panasonic 70-300mm are 17 elements in 11 groups (2 ED lenses, 1 UED lens, 1 UHR lens), minimum shooting distance 0.54m (at 70mm) /0.74m (at 300mm), maximum shooting. It seems that the magnification is 0.5 times (at 300 mm), the filter diameter is 77 mm, the size is φ84 mm x 148 mm, and the weight is 790 g
