After emailing my dealer on Monday, I got this reply

Hi Richard,

The Focus RS(the new one) is not out until next year and as yet we have no idea on pricing.
It is unlikely Ford will offer any kind of Privilege discount as the car will be neash and therefore Ford Mototr Co. will probably feel as though they could sell them easily without needing to offer anything off. However, this is only hearsay for the time being.

If you want to purchase a new Focus RS then we are taking orders with a £500 non refundable deposit and then it's a case of waiting for build/prices etc....

Let me know what you think.
