Team-BHP - Torque vectoring twin clutch system by GKN

Came across this article on Top Gear. The technology sounds very promising and affordable. Can the experts shed more light on its actual practicality and whether it will replace the limited slip differential soon?

The beauty of GKN’s clutch system is that, for a small weight penalty, a car can actually ‘vector’, or infinitely juggle torque between each wheel, rather than the more simple cheating way of braking an inside wheel on a corner to load up a mechanical differential.

Using the brakes wears the pads out and, well, brakes the car. It slows you down. The RS, meanwhile, deploys its army of clutches and varies their open/close position, shuffling more power to the wheel that needs it – 100 per cent of the power of that axle to one wheel, if needs be.

“Yes, absolutely,” Ray replies. “We supplied systems like that to the BMW X6 and Lexus LFA. Theoretically, you could have a completely solid rear axle, with independent clutches for each wheel. We’re only at the start of developing this technology. This is really a building block…”

If you read the article, they mention it is already featured in Range Rovers, it is promising but i don't think torque vectoring is cheap. It is quite complex and with loads of electronics which will make it expensive. Yes this is the future of ESP, whereas ESP corrects after a situation occurs (reactive), Torque Vectoring and similar systems are more predictive and does the correction before a situation arises.

I don't think it is that expensive. The Focus RS is priced around $35k. And like the company says, this is just the beginning. So the prices should eventually come down, right?
