Nope, I just saw that they are going to release the MCX-L, ultra-low power series, apparently kinda in the same league as the STM32U5 (same ARM M33, "similar" power consumption figures), but as far as I've seen, they are going to have limited Flash & RAM compared to the STM32U5 and a limited set of peripherals, so not really excited at this point. OTOH, they seem to embed a second, M0+ core.
