For those who have an extra $1.2M rattling around in their wallet, a used Leica Luxus II of 1930's vintage will be auctioned off in Hong Kong with that as the expected result. It's gold plated and there were only four made. I guess my 6D won't be worth that much if I hold on to it for 85 years. Interesting story, though. http://www.bbc.co.uk/news/world-asia-25046060
