BCNranking (google translation here) posted the full 2013 market share analysis. In the mirrorless category Olympus is leading the group closely followed by Sony. The big change is the 9% share drop fro Panasonic. Quite a bad news!
It will be interesting to see if the Sony A7-A7r series will have a major impact on 2014 sales. My guess is that Sony could become number one in Japan!
