Apple did say PCIe Gen 6 - in the original version of the press release. That's where the quote came from. But they have now changed it to exclude the reference to Gen 6:
"Storage performance is up to twice as fast, with a next-generation SSD architecture, delivering industry-leading read and write speeds for rapid project loading, file transfers, and loading huge LLMs."

So it seems like Apple made a mistake in this case. I agree with you that it will likely be PCIe Gen 5 - that's much more logical.
