I have heard nothing. I see that NXP recently announced the apparent Kinetis L successor (MCX L), with the FRDM form factor boards available. However, there sure are a lot of other interesting Cortex-M-based microcontrollers available from Raspberry Pi (Pico), Renesas, STMicro, Infineon/Cypress, Microchip, TI, etc...
If I do ever hear anything, I'll update this thread.
