I've followed the proliferation of 24 megapixel APS-C sensors with great interest over the years. Indeed, this is a great interest to many people. From what I know, between Sony and Toshiba there are at least a half-dozen different 24 MP 1.5x crop sensors out there. The entire Nikon DX lineup is using a nearly identical sensor, Sony has its A6000, and Pentax has the K-3. All of them perform similarly, with certain models here and there having flukes of shadow banding, or excessive high ISO chroma noise / banding, etc.
If Nikon's latest iteration, the D7200 is any indication, the K-3 II stands a chance at being one of the best sensors on the market, crop OR full-frame. Even the slightest improvements in DR and high ISO above the K-3 will put it towards the very top of the heap, and leaving even generation-old full-frame shooters scratching their heads to see a difference.
That's partly due to the K-3 sensor being no slouch, of course, and there will be absolutely zero shame in taking advantage of any flood of used cameras that may hit the market in the next few months after the announcement. I know for darn sure if I were a Pentax shooter / switcher, and if I was any less into astro-landscapes and stuff, ...I'd jump on a used K-3 within the next 6 months for sure.
