This is filed in the rumor category so take it with a grain of salt.
We do know that the Nikon D850 DSLR will shoot 8K time-lapses. Nikon has released a video on this camera.
Some of the key rumored specs are:
- 46MP sensor
- Full frame 4K video WITHOUT cropping
- NOT a hybrid EVF/OVF as some were hoping
Time will tell.
