   It's nice how they've integrated more stuff into the SiP, so you can make   
   things smaller.  The trouble with the original Pico was that it took up more   
   board space than say an ESP32.   
      
   Now, if somebody would do a module pin-compatible with the ESP32 modules   
   that includes wifi, then things will be Very Interesting.  Looks possible -   
   there's a board with the RP2350 and an ESP32-WROOM side by side which shows   
   the comparison:   
   https://www.switch-science.com/collections/%E3%83%9E%E3%82%A4%E3   
   82%B3%E3%83%B3%E3%83%9C%E3%83%BC%E3%83%89/products/9796   
   and there might be space to get the wifi chip inside the footprint.   
   Couldn't say whether the RF performance would let you though.   
      
   What's nice also is that it's a Proper Arm Chip, rather than the weird   
   Tensilica Xtensa CPU architecture in the base ESP32s.  Some programming   
   languages like Rust are better supported on Arm than on oddball CPUs.  ESP32   
   have gone to RISC-V for some of the newer ones (but not all, so you can't   
   get all the features with a RISC-V CPU) which is better, but with the RP2350   
   you get all the boxes ticked in one package.  Aside from wifi, of course.   
      
   (apparently the wireless version of the Pico 2 is due end of the year -   
   meanwhile people are putting RP2350s with ESP32 modules on boards like the   
   above.  Maybe RPi have do some certification work before releasing).
