We should see the new Canon mirrorless next Monday, details are still being confirmed about specifications and all that.
Don’t expect anything too “retro” or “rangefinder-esque”, as this is going to be a mass market consumer electronics type of camera. It’ll be more Nikon 1 than Fuji X-Pro 1.
I will post more when I can, a lot of what’s going around is pretty contradictory. Canon seems to have done a good job plugging leaks. :)
