Yes, but there are other benefits to a carbon fiber shaft besides being lighter in weight (which is still pretty damn substantial, compared to weight savings on other rotating bits of mass like the wheels). Apparently they are more elastic, and can twist more without failing than an aluminum shaft. The same elasticity apparently makes smooth shifting easier too, from what I've read.
I've driven cars with carbon fiber driveshafts, but never replaced a stock steel one with carbon fiber. I'm eager to see the difference for myself. Is it worth $1000 to some people? Probably not. But then again, there's a lot of money people spend on their cars that I can't fathom myself, so each to their own.
