I maybe an young old school photographer. But the point is, high resolution high frame rate camera present a contradiction to solve. Without solving the contradiction, it is easier to make camera with lower resolution fast frame rate and high resolution slow cameras. The K1 (or D810) sensor is an example of a tradeoff by dual mode acquisition sensor (1 crop in the center at faster rate or whole sensor slower). I once suggested to use hardware decimation after the sensor to deliver variable frame/rate resolution tradeoff by software feature option, but so far no one made it this way because the image sensor is the bottleneck, large sensor is too slow to output frame fast enough up front the decimation.

Important note: photographers better spend their money into going to photography workshops so that to frame / compose correctly, as opposed to buying an expensive large sensor camera and crop the frame to lower image quality.

Not really, the G1 X Mark II does have about 13Mpixels, but is far from large pixels and ultrafast frame rate and it is not an ILC / long lens. The kind of camera I described doesn't exist.

Following that logic , a 4K sensor with 5um pixels would be 19mm large, almost apsc size. Would be interesting to see a 4K dedicated apsc sensor, 6.1u pixels, with high frame rate what allow high speed frame capture to allow high speed CDAF @ 60 frames per sec. (no PDAF needed). Would make it a good solution for video, but also great solution for wildlife shooting e.g with a DFA150450. 6.1um pixel would deliver good high ISO quality. AF and AE based on fast image sensor (but 4K resolution only) would make it possible to continuously improve via firmware updates. 4K res. would be enough for most users who post on the web, tablets and phones and even printing.
