That's nonsense.
Yes, I'm sure that Dale Photo are wanting to clear inventory ahead of the Photokina announcements and possible new models, but to post fear mongering comments about Truesense, the former Kodak subsidiary, is reprehensible. Truesense is a strong and well financed company that continues to produce sensors for both the M8 and M9, and will do so for years to come. Even if a new M10 uses a sensor from another manufacturer the purchasing department at Leica will continue to place orders for KAF10500 and KAF18500 sensors.
If at some point in the future Truesense decides to discontinue production of one or both of these models then Leica will negotiate with them for an "end of life" buy, which would stock their shelves with enough inventory to support repairs for decades.
In 20 years my TV, my mobile phone and my computer will all be long retired to the scrap heap, but I have no doubt that my M9 will still be producing amazing full frame images.
