Leica issued a third update on the M9 / SD card compatibility issue. It seems that they have isolated the problem and a new firmware for the Leica M9 will be released for testing in few weeks:
STATUS 11.10.2011 (Update of the report from 8.8.2011)
Thanks to the close collaboration with SD card manufacturers, Leica has now managed to rectify the fault by making adjustments to the firmware. To ensure compatibility with as many cards as possible and to ensure that all the related processes remain fault-free and are not compromised, comprehensive testing must be carried out in the development phase.
In the coming weeks we will test a beta version of the firmware in practice in cooperation with affected and selected customers.As soon as the firmware solution is proven in practice, we will name a date for the release of the update.
