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
