Interesting timing, with declining camera sales in general. With industry publications claiming that mirrorless will replace traditional dslrs. (Though mirrorless growth isn't exactly leaps and bounds either).
Every dslr camera maker has taken a different direction to remain profitable through the shrinking camera market: Sony has nearly abandoned traditional dSLRs, and is betting the house on mirrorless, especially full frame mirrorless where they are basically alone. Nikon has pushed rapid succession of full frame models, trying to "upsell" their customers into more expensive camera bodies and lenses. Canon, as the market leader, has somewhat taken a more passive role, reacting more than acting -- but they have heavily focused on continued APS-C development (the 7dii, and they are about to launch 2 new 24 mp Rebels), though they are now going mega high resolution with 50 mp, and they are basically re-launching their own mirrorless. So Canon seems to be trying almost everything, all at once.
I'm very happy for Pentax users. And happy in general, because more options are good for all of us. Though I wonder how successful this will be for Pentax -- What about a full frame Pentax, with only 2 native lenses, will attract *new* users? Will it be a huge seller to current Pentax users? Those who lusted for full frame, probably mostly weren't shooting Pentax anyway... And most of their lenses will only work in a crop mode anyway.
