Technology has gotten more precise over the years. You can transmit quite a bit of data over just a single serial wire. They've more or less figured out how to encode quite a bit of data accurately. In the USB 1.0 days, not so much... 
That's interesting that they added five pins for USB 3.0. I suppose that USB 3 devices then must have to have a mode where they can send their data using only the original four wires (for backwards compatibility purposes), and only use the extra wires if they detect that they are running on a USB 3 port.
