USB 3.0 coming, 4.8 gbps!
As of now, today's USB cables aren't fast enough for such heavy transfers, sending data at 480 megabits per second. USB 3.0, on the other hand, will increase that tenfold to a whopping 4.8 gigabits per second. The fancy new cables should start hitting shelves and being used in devices around 2009 or 2010.
