On the D810, they were 12 bit 'uncompressed' (but really only 11 bit and more like a JPEG) RAWs with baked in WB data. It would be better to think of them as a JPEG with extra data than a true RAW. The manual also states these images cannot be retouched. It also requires more processing horsepower, which is why the buffer roughly cuts in half on the D810 even though it's producing a much smaller file size. These were really quite useless because you could just shoot a 12bit compressed RAW and get similar file size but with about 4 times the data and better everything else with a proper RAW.
Now, on the D850, the small and medium RAWs appear to have some important changes. They are now lossless compressed 12bit RAWs and Nikon support claims you can adjust the WB in post (this has yet to be confirmed). The D850 manual also does not have the caveat that the small and medium RAWs cannot be retouched, like there is in the D810 manual. It also seems like they are using pixel binning, which is also different than how it was previously done (down sampling). This could potentially produce a fully usable RAW, but just at a lower bit depth and of course lower resolution and file size (which is the point). If file size is the sole concern, you are likely still going to be similarly benefited just shooting compressed 12bit, but some people are also after the resolution decrease.
One inconsistency I have noticed already is that Nikon themselves had said in an interview that S/M RAW reduced buffer depth, however is not the case according to the manual even though they take more power to process and still read the full sensor. There is however an inverse relationship between RAW size and buffer depth due to the extra processing involved. Small RAW gives you 56 images, medium 94, and large 170. Buffer clearing time is also longer on the S/M RAW, however the full buffer filled with regular lossless compressed 14bit full resolution images can clear in 7 seconds which is very fast.

will we not know until LR or Photoshop is ready for this camera?
I have never used any other software, ever!
