I thought that they were going to use the RP2350B on the Pico 2 W.
The 2040 (and 2350A) doesn't have enough GPIO pins for everything it did on the Pico and interfacing with the wireless chip.
Therefore some internal functions have been moved to the wireless chip's GPIO pins. It also didn't have an interface to the Bluetooth part of the wireless chip.
So when the 2350B chip with 48 GPIO pins had been announced, I thought its purpose would have been to use it for a new better Pico 2 W that wouldn't have had the same limitations.
But apparently I was mistaken.
