There seems to be an expectation or underlying current of knowing that Canon will deliver a DSLR that has a "more" of something this year however it remains to be seen if that "more" translates into a good enough IQ increase that it will distract people from Sony.
Some people posting on Internet forums do certainly seem 'distracted by Sony'. However, that sort of thing doesn't seem to be having a big impact on people actually buying cameras. Which group do you think matters to Canon?
It is only a matter of time before Sony turns the "distracted by Sony" into "buying Sony."
People won't be happy with themselves if they've been thinking "wow, that Sony produces the nicest pictures" and then end up buying something else.
Every time I log onto a social media I'm seeing more and more posts saying "Selling my Canon, Just got a Sony A7R/S" which does seem to have an overall impact on people who are buying cameras.
