There are/will be boards with the RP2040 chip also in the form factors of Pro Micro, Feather/Thing, ItsyBitsy and Arduino Nano, with different capabilities.

The RPi Micro is the cheapest though, with "only" 2MB flash but the most GPIO pins.
The Arduino Nano RP2040 Connect board seems to become the most expensive, with 16MB flash, a nRF radio module and an accelerometer.

Doesn't seem that special, and the idea from their PIO block seems copied from XMOS
Cypress Semiconductor has a similar capability with their PSoCs as well. Given that, the Raspberry Pi and Arduino platforms have never succeeded based on novel capabilities. They've succeeded because they are cheap, accessible, and they work well enough to get people excited. If they can make the PIO block easy to use, and keep the responsiveness in the sub microsecond range without requiring the user to muck around with interrupts I can see a couple of my own use cases for it.

Wait what? Am I just dumb or doesn't the Arduino Nano have like 32KB flash, not 16MB? And accelerometer? In a nano?

The bus fabric allowing full speed from both micros and devices is what I saw as unusual and noteworthy. This is not a device for the arduino user, but someone who needs fast real time processing. PlatformIO will probably be the development environment of choice. Even though the core is M0, they added hardware multiply and divide which is very nice too.

'(I’m not aware of other dual core microcontrollers at this price point)'

You've never heard of the ESP32? It's been around for a while, Dual Core and even faster than the Pico. And a third of the price.
