Any rumours of a 5?
“Don't expect a Pi 5 five next year,” Upton said [in December 2022], explaining that the Pi team sees 2023 as a year to spend “recovering from what just happened to all of us [COVID, supply chain issues].” https://www.theregister.com/2022/12/21/no_rpi_5_2023/
It's reasonable to expect the 5 to arrive in 2024 at the earliest. Personally, I wouldn't expect super fast m2 ports and whatnot.
Frankly, at this point I am ready to spend a bit more and get a proper 5800u mini pc or something. Waiting for AMD's Zen 4 APUs to hit the market. They are not going to be cheap, though
My expectation is 2025 at the earliest, tbh. Mostly based on the CEO's repeated statements, and the complete lack of rumors about any developments. If a new lineup of PIs were going to launch next year, they'd have to be pretty late in development already.
Put all the high-performance work into the CM units of different specifications. Make (or encourage the market to continue to make) mainboards that take those units. Maybe certify a couple of them for the Foundation's use.
And then focus on making microcontroller-level chips at different performance levels, up to an "alternative home computer" device. Something small, which can be learned completely. Enough power for something equivalent to a Minix or a CP/M or RISC OS. The RP2040 is almost there anyway.
