We all knew this was coming, but my question is what's the topology? The same as the regular Pi5, with the RP1 southbridge built-in and only one PCIe lane exposed for the user, or does the CM5 leave off the RP1 and break out all five PCIe lanes for user shenanigans? They have a bare chip supply chain set up from the RP2040, so they could sell the RP1 separately for those who want to integrate it onto their carrier boards.

I've been waiting for this, now, the question is, is this a drop-in replacement for the CM4? If so, these will sell really well (and will have shortages)

Eben Upton was refusing to be drawn on specifics when Jeff Geerling and others chatted to him [1] about roadmaps recently. Nevertheless, the rumor is that CM5 will be drop-in compatible with the CM4, the details of that have been available via their NDA portal [2] for a few months now, but I think even this leak on Twitter (just a box with a label) is a breach of an NDA / embargo, so we might not know officially for a little bit yet?

What's something you do with these compute modules (CM)?

They get installed in stuff like the Home Assistant Yellow, or the Timecard Mini.

It looks like the CM5 still has one PCIe lane. https://pip.raspberrypi.com/categories/945-forward-guidance

Build products with them. I know of a few musical instruments with CM3s, for instance.
