even though it would be optical, it still is using PCIe protocols in the background...

How could you possibly know exactly what protocol they'd be using for the potential future optical PCIe connection? Your guess is as good as anyone's, no?

  • Probably because optical PCI-E is an old thing by now.

    In fact, "zero~th generation" of thunderbolt used optical link, too. Also both thunderbolt and DisplayPort reuse a lot of common elements from PCI-E
