Hello Joseph: There is in-depth information about the Panasonic-Olympus cooperation at dpreview.com. As you now know Leica has built a new lens to take advantage of the "4/3" system that the "P-O" cooperation is building upon, and such lens is to be used on the Panasonic SLR which was also just annnounced. Hence, it seems reasonable to conclude that there is an exchange of information between all three companies. Indeed, one would certainly expect to see additional Leica lenses for the 4/3 system. I have not been able to ascertain the cost of the new Panasonic SLR with the Leica lens.
Best wishes,
Elliot
