ok thanks 👍 sads, i hope some news on that still emerges

There are many improvements in the rpi5, particularly in communications from what I have seen in reviews. It is quite possible there are some options or soon will be for adding PCIe4 (there is RAM firmware available for this, iirc) You may wish to do your own research to read what people who have the RPi5 have to say.

Another thing is to learn about the CM4 (and, I assume, the CM5 because that is a lot more useful to industry) and how they can use RAM on their mounting boards. In theory, that should be exploitable too.

i just need 16gb RAM for my use case. so i'm hoping it'll eventually be available

Well, I do not know your specific use case, or how fixed that number may be, but in a worst-case scenario and understanding the dramatic performance costs you can use storage as swap to artificially 'add RAM'. An m.2 SSD on that PCIe will certainly reduce performance, but it will accomplish the job - the machine will do the work. Depending on the use case, assuming the upper 8GB of RAM is on-demand, compressing RAM and not relying on performance tricks like RAM storage, may let your project run mostly in native.

Sooo many ways to do the thing with what you have, if not what is required by spec! gotta love FLOSS.
