pro enough never to sell?
these sell is such small quantities why would canon even bother?
I don't even think the Fuji Xt1 even makes a blip on bcn's japan rankings let alone anywhere else.
I mean, here's a news flash .. the people that hang on in dpreview, cr forums .. aren't the mass buying public. while it's certainly good to tailor to us if you have no market (like sony, Fuji,etc) does .. it's not exactly profitable for Canon or Nikon to migrate R&D away from other areas, nor does it build an installed base in the lens mount.
MILC / Small FF is even more against what canon is saying they wish to do with MILC - which is to get it even smaller.
Japan is a different market, full of gadget-lovers. Things have to be tiny and shiny. Functionality is not so important, as long as something is "brand new", "cute" and available in 16 different colors or perfume-bottle shaped.
I think that is a little bit of an over simplified and perhaps stereotypical view of the Japanese market. I don't disagree with you fully, you certainly have a point about the "cute" and "different colors" thing but that doesn't represent the majority. They do tend to follow trends and when something becomes trendy almost everyone ends up owning it. Like the iPhone.
When it comes to cameras though things are a bit more traditional as this is the land of cameras after all. I still see a whole lot of DSLRs , in black kicking about. Way more than colorful mirrorless cameras. Spotting an EOS M is a fun game for me and I get excited when someone else has one! I'll admit it has mainly been women that have owned them and sometimes I feel like shouting "my other camera is a 6D! Honest!"
