I wonder if they plan on transitioning fully to RISC-V in the future, it would be cool if that cuts the price down by $1 or so. The Pico series is the only Raspberry Pi product line that interests me these days. Love seeing the increased speeds with decreased power consumption, and the additional PIO state machines are a nice touch. Looking forward to seeing the Pico 2 W!

I believe they got a $0 license for the M0+ cores in the 2040. Don't know about the new 2350. The addition of Risc-v cores might be a flex to defend against future issues with ARM.

Going from two PIO blocks to three seems timid. Why not hundreds, like one for each gpio pin? And maybe redesign the PIO to allow more than 32 instructions? They are tiny, anyway.

Anyone know if there is any software for the Risc-v cores so far? Compilers, Micropython, etc.
