Mirrorless cameras are disrupting DSLR's, and smartphones are disrupting the point and shoots (and possibly mirrorless cameras in the future - 10+ years).
Mirrorless cameras have been stealing some sales from DSLRs, but not as much as anyone thought it would (or hoped). DSLR sales are collapsing on the other hand, in a pretty dramatic way.
People aren't trading the bulky DSLR in for a svelte mirrorless, they're trading it in for their phones. It turns out that a large portion of the amateur DSLR market is dominated by people who are now perfectly happy leaving their gigantor kit at home.
Contrary to what Canonikon et al predicted, the entire low end of the market seems to be collapsing - DSLR, mirrorless, and all.
