Sony VAIO Z [1] does exactly this - it uses Thunderbolt-over-USB-plug to connect external Radeon 6650M and Blu-Ray Burner.
But I'm also waiting for cheap ($200 max) Apple-compatible PCIe enclosure, so I could play newer games on my 13" MBP. I don't really want bigger screen and more weight and don't really need more power that 15" gives, but playing some game from time to time would be nice.
