The Japanese Yen has fallen considerably in value in recent months. Japanese exports should therefore be much cheaper now for buyers, so why are Canon prices remaining so high? I'd love a new Canon 5D mk III but current MAP limitations are keeping prices high and stopping me from buying.
The Japanese (or South Koreans/Chinese) do not abide by the same competition rules as the West whether it is cameras or shipbuilding!
I am not saying prices will not fall but they might fall at a time to suit the Japanese camera companies - certainly not the Western consumer.
In any case the Japanese who have not experienced monetary loosening on the same scale as US/UK etc - until now - have had to suffer sky high yen which was damaging exports.
Unfortunately it does not look like their will be any real competition to Canon Nikon Sony etc from S Korea or China so the Japanese rule the roost for a very long time to come. No competition obviously from the West either as preference is given to the financial sector ie money churning rather than industry (Germany excepted).
