Well, powertrain and superficial design differences aside, DEW is still the basic architecture for the car. The floor, the wheelbase, and the rest of the bones are the same. Jaguar is incredibly skilled at massaging old platforms for modern use, like the XK8 (and Aston DB7) which were both closely related to the aging XKS that preceded them. It's a strategy that's kept costs down, retained customers, and protected the brand's identity.
Tata's timing was brilliant as the bulk of the development for the new XF, XJ, and Range Rover Evoque were completed under Ford's direction and financing by the time they took over. Fitting since BMW had finished the development on the L322 Range Rover when the Land Rover brand was sold to Ford for a pittance. I believe Tata will continue to be a good steward of both brands.
Why Lincoln hasn't been able to turn DEW into a current-day Cadillac CTS-fighter is beyond me. As demonstrated by Jaguar, the wheelbase is right-sized for the class and the platform is more than rigid enough to support a high-powered 2010+ sport sedan, one that's vastly superior to the Lincoln MKS.
