Perhaps, if there is an M11, they decided to wait until November 18th. Why? Because there is no 18mm prime lens in the M line ATM. Perhaps they're going to announce one? And perhaps they deliberately decided to launch both on the 18th, with November standing for the 'M11' and the 18th standing for the '18mm'. I also wonder if the TL and CL lines are going to be discontinued. The lenses won't be, I don't think, because some people might want compact options to shoot with their SL cameras in APS-C mode. Or, they might be releasing a compact body with a 36mm sensor, kind of like the Sony A7C.
