Well, the Chicago Auto Show at McCormick place has certainly seen its share of Lincoln debuts over the past years and more so when Mercury was alive. With that being said though, less and less has been introduced by Ford @ Chicago as FoMoCo has been debuing more products in Detroit and New York. Maybe Auto Blog knows something OR they are banking in the fact that the Aviator will be made in Chicago, so they are tossing that plant a bone by introducing it there. That might make some sense.
Otherwise, I wouldn't put too much faith in booking a place ticket or hotel room in Chicago just yet,
