UPDATE: There was an error with the google translation tool. Olympus leas the mirrorless market in Japan (not the DSLR+Mirrorless market). They currently have a sales share of 38.7% and do beat Sony, Panasonic, Ricoh and Leica.
But there is a lot to do for Olympus. They have to translate the success into the rest of the world and work on a new sensor!
