According to the latest rumors, the Fujifilm X-T3 mirrorless APS-C format camera could get a 26MP multi-layer CMOS sensor. The new camera is expected to be announced in September at Photokina 2018.

A multi-layer sensor, unlike a conventional sensor, has a layer to collect image data and a layer dedicated to processing that data, allowing high-resolution cameras with such a sensor to perform much faster. This technology is one of the reasons why the Sony A9 is able to achieve shooting speeds of up to 20 frames per second.
So, if the rumors are true, the Fujifilm X-T3 will be the first APS-C-format camera with a multi-layer sensor that will have faster focusing and shutter speeds comparable to the Sony a9. The camera is also rumored to lack internal IBIS image stabilization.

26MP APS-C X-Trans CMOS multi-layer sensor
Improved X-Processor
No IBIS
Extended ISO base range
Serious shooting 14 fps
4K video at 60 frames per second
