Actually no, not the same situation at all, for many reasons:

The 15C already had proof that a re-issue will sell out quickly: the 15C LE !

The 15C had many more years to gather fans, and it's RPN (vs. RPL) so in demand by a much larger audience.

Finally, in the case of the 15c CE, Moravia could repurpose 12C hardware since it's still in production.

For a new kind of 48GX++, with enhancements, it would mean developing the h/w from scratch and basically redeveloping the ROM, nearly from scratch. So, orders of magnitude more investment would be needed, and I don't believe anyone could justify such. Just my opinion though...

I understand it from a hardware perspective, but why would there be a need to redevelop the ROM, since it is already running on the ARM from 50g?

The latest 50g ROM, when last updated (2.15 IIRC), had less than 10 bytes of available space, so adding any enhancements would mean major refactoring before even starting on the new features. And both Tim and Cyrille have commented that mods to the 50g ROM were extremely difficult as it's highly patched state is very frail and nearly any change led to other undesirable side-effects, etc. So, many man-years of effort by folks with System-RPL and likely both Saturn and ARM assembler experience would be needed. Not impossible, but also not cheap.
