This is what I can't get past. The majority of people are happy just using their phones. Serious enthusiasts are more likely to go for DSLRs.
DSLRs dominate in the US, but mirrorless is doing better in Japan. So it's not clear that DSLRs automatically win the high end amateur market.
The point-and-shoot market is over-saturated already and being eroded by phones. So, where do these mirrorless cameras fit in?
Yuppies and enthusiasts who want a more compact camera. Basically, the high end amateur market.
I can't shake the feeling that the Sony, Panasonic, etc. mirrorless represent a transitional technology. I've no doubt that Canon is watching the market closely and if and when they jump in, they have the resources to offer a category killer if they choose. I'd love to see what their market research shows.
They no doubt are watching the market, but if they went for a system camera, they would need to develop a camera, a new lens mount and a decent assortment of glass. Even then, it won't be a category killer to begin with because much like Sony, they will trail m43 in their lens offerings.
