We will have to wait until the end of the year to get more information unfortunately but it looks like the rep gave some interesting clues on what to expect. Even though the navi concept looks completely different from the current navi and the spied 18 expy from last yr, going off the continental concept from last yrs auto show and how similar it looks to the production version (same for atlus concept and f150 production model) its safe to assume that the navi will be most the same with minor differences, safe some production pieces that is seen on the continental production car. I think the main question now is what new features will the trucks have and how much different the navi will be from the expy. Im thinkin the navi will be more carlike (fusion of bof and unibody) to help replace the mkt which is unibody and the expy will be more rugged bof but refined
