Building a WIFI module inhouse is expensive. The certification process is tedious, lengthy, and expensive. Which is why you see the “Pico W onboard” products. I’m not saying it won’t happen, just that it may be tricky to do. Is it worth the cost to develop and build it?
I’d love a faster updating version (I’m happy to go grayscale for it) version of the Inky Frame 7.3"

I wish there was a Pico with inbuilt debugprobe. OK, PIO 0+1 would be taken by the probe but a second pico and the probe could all be powered via one USB. It’d also need an extra BOOTSEL for the probe and a reset on the non-probe would be nice.
Basically this on one package (with headers?)
You could debug on the combined solution then deploy to a normal pico
Great for messing about with things like an omnibus and some packs if nothing else…
You mean like the STM Nucleo boards have?
Even if the Pi Debug Probe had power out in some way, that would really help. I know there are reasons why you might not want power on the debug cable, but the target is going to need powered somehow, it seems odd to leave that out entirely.
I’ll have to look into those but really was after a 2040/2350 device
If something like this was available in a case you’d have something a consumer could learn to program in C/ASM etc on without any fear of soldering irons. Would even expose the slave processor (except 0+1) externally for easy plug+play expansion
Closest I can find is RP2040-GEEK Development Board | The Pi Hut but the example connection diagram to a pico looks dodgy (connecting gpio1 to gnd + vice-versa?)
Wish list
Tiny 2350 with WiFi
Pimoroni Pico plus 2 W but with lipo charging (like the Pico lipo that you guys did)
The next badger 2350 W with lipo and a choice of screen 7/3/2 colour epaper

I think this is a simple error in the connection diagram.
I am developing on a Pi using a self-designed hat: GitHub - bablokb/pi-pico-devboard-hat: A PICO devboard-hat for the Raspberry Pi
YES! Those are exactly what I would want!
I wish Pimoroni would update the 1.14"/2.0" Display Packs to have same GPIO6:7(I2C), GPIO20:21(LCD control), GPIO26:28(RGB) pinout as Display Pack 2.8"
Wristwatch (similar to bangle.Js) Definitely with an RTC, and preferably with touchscreen and Qw/ST. Maybe even GPS and/or clipper? Hopefully RP2350.
PicoSystem 2: original but RP2350 also with bumpers/triggers, Qw/ST on back, RM2 for Bluetooth/BLE/WiFi, and adjust/menu buttons like the Qw/ST pad has. Maybe also rumble.
A battery powered Enviro Armband would rock my world. Time, temperature, humidity, and barometric pressure; displayed on a color LCD. Onboard BME280 and RTC. I have multiple Pi and Pico based weather monitoring builds scattered about my domicile. One by my front door shows me what it’s like outside. Once I’m out the door though, I don’t currently have anything that is easy to carry and or pocket friendly. Something strapped to my forearm to glance at with real time readings would be so cool. No pun intended. :P
Have a look at Welcome to Unexpected Maker
You cannot expect this to work with a RP2xxx, these chips are not optimized for low-power operation.
Maybe have a badger/tufty but with a touchscreen?
I was wondering if anyone had made an adapter to allow Pico add-on boards to work on the regular Pi series of products (or compatibles). For example, something that would let the Pico Audio Pack be used on a regular Pi.
In an attempt to find such an adapter, I found the Using Pi-Hats together with a Pico discussion. That involves the corresponding solution of the use of Pi hats with a Pico. Maybe I missed discussions about what it is I have been searching for.
The Pico seems to get a bit more attention here at Pimoroni these days, particularly since the era of well-publicised shortages of things like the Pi Zero that drove product development over to the Pico for a while, so is it not time to let the Pi (and compatibles) take convenient advantage of the growing Pico ecosystem?

Mechanically, my Pico-to-Pi-Hat adapters could also be used the other way. But unless the Pico-addon uses the correct Pico-pins that are matched with the corresponding Pi-pins, it won’t work.
And that is actually the reason why there is no Pi-to-Pico-Pack adapter: the pins of the Pico can be repurposed, e.g. there are many ways to define I2C pins. The adapter could only map a single pair of pins, but if the Pico add-on happens to use a different pair the adapter is worthless.
Now having said this: Pimoroni uses a fairly standard set of pins, so there might be a chance to actually create an adapter that actually works with their Pico-Packs.
Needless to say that the next step is even more challenging: write drivers that make use of the Pico add-on.

Looking at the Raspberry Pi Pico Pinout I can see that there are many places that a Pico add-on might expect signalling of a certain kind, due to the way that the microcontroller exposes its peripherals as alternate functions in numerous places.
The function selections do appear to be fairly consistent, though. For example, UARTn TX always seems to appear with I2Cn SDA and SPIn RX. This kind of thing makes interoperability with other microcontrollers and SoCs challenging, but that is another matter.
But I agree that it would be hard for a regular Pi to cater to all possible expectations of Pico add-on boards. Constraining signal assignments to those used by a given supplier with their own standard, like Pimoroni, might work, as you say. With so much flexibility, someone has to create order from chaos!
Anyway, it was an idle suggestion and useful to contemplate in a bit more depth, so I appreciate the analysis!
If you can solder one of these may work.
Adafruit Perma-Proto HAT for Pi Mini Kit - No EEPROM : ID 2310 : Adafruit Industries, Unique & fun DIY electronics and kits
I have one wired up to use a Pimoroni Pico Display Pack on a raspberry Pi. I only wired up the SPI pins. I didn’t bother wiring up the buttons or RGB LED. A display Pack, Display Pack 2 and 2.8 all worked on SPI 0. I wired it up to test if it would work. I have plans to use 3 Pico Display Pack 2.8’s on SPI 1 on a Pi.
For the final build the displays will be mounted on these,

This is possible, but adds some extra challenges. You should google for “raspberry pi more than two spi devices”, there is lots of advice as what to do. See for example https://forums.raspberrypi.com/viewtopic.php?f=44&t=98318&start=25#p821666 (this is from a Raspberry Pi engineer and therefore highly valid, but it is an old post and things might have changed the last ten years).
And don’t forget the pullups on the CS. It could be that the redefinition of pins as described in the post I linked to takes care of this, but I am not sure.
