Clever how they manage to run DisplayPort and PCIe at the same time on the same cable. Apple also somehow manages to overload the same connector with VGA and DVI. Also, I expect this will push Apple's Mini DisplayPort toward becoming a true industry standard.

Because they've got PCIe on the same cable, I'll bet we start seeing monitors with a lot more logic inside them, so you can connect all your USB/Firewire/eSATA devices and whatever else to the monitor, then you click your laptop in and *foomp*, it's all there. The only thing missing from Thunderbolt is power. Otherwise it would be a single-connector docking solution.
