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." Here's the original, archived press release from August 25th (look under "Blazing-Fast Storage and Pro Connectivity"): https://web.archive.org/web/20260825130329/https://www.apple.com/newsroom/2026/08/apple-introduces-new-mac-studio-with-m5-max-and-m5-ultra/ https://web.archive.org/web/20260825130329/https://www.apple... And here's the first modified version that the Wayback Machine has, from August 26th: https://web.archive.org/web/20260826020313/https://www.apple.com/newsroom/2026/08/apple-introduces-new-mac-studio-with-m5-max-and-m5-ultra/ https://web.archive.org/web/20260826020313/https://www.apple... 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.
