Damien,
I'm afraid the people who write the leases are a cautious bunch and therefore as Paul says if you plan to keep the car for a longish period you might as well take the residual risk as I can't imagine the reality will be as bad as I suspect the leasing guys are working into their calculations.
On top of that if you are considering a personal lease there's the dreaded VAT to factor in as well. That, however, can be less of a problem if it's going to be a company funded lease
