I, for one, fully comprehend manufacturer/retailer relationships. However, I'll never believe Canon does not have some hand in this particular move. To think B&H suddenly got a wild hair up their tookus one day and fire-saled the M and then their competition followed the piper like mice is far too improbable. This is why I initially said I'm scratching my head trying to understand this. There is something behind it -- and I know all (or some at least) will be revealed in time.
Meanwhile, while I think it would be delightful to have the M right now, I'm not taking the bait. For me, it won't get me any pictures I can't get with my current equipment.
I was quite surprised by how many people came out and, at least publicly, said they were buying the M camera, either to keep, sell on later, or some other reason. It was almost as if everyone had US$300 burning a hole in their pocket which they just had to get rid of.
Sure the new M is likely to be more expensive, but then it is also likely to be better.
Look at the much more costly - some say much higher IQ - RX 100. Sony has just come out with the RX 100 ii which addresses some of the main issues customers had with version one. It is a little more expensive than v1 but many would be happy to pay that extra for improved performance.
I have never been impressed with the M, and I was not even aware you needed a mount, a this and a that. The whole point of these small things is that you stick it in your pocket and not worry about which bits you have left at home.
I will look at the M ii when it comes out, but until then, I do not care if the M I is US$ 100, I still won't buy it.
