Here is a lens diagram comparison between the EF 50mm f/1.8 STM and the upcoming Canon RF 50mm f/1.8.  The new RF 50mm f/1.8 STM definitely looks like a brand new lens design and not simply making the EF mount version work with RF, which likely would never be worth the time and effort anyway.

As pointed out by forum contributor privatebydesign, this is a “double-gauss” lens design.

I expect to see this lens announced next week, if not sooner.
