As is the case with every auto show, we hear rumors about what will -- and what won't -- be revealed there. And with a show as big as the Detroit auto show, we have been overwhelmed with news bits and pieces. We know there are going to be new vehicles in the entry-level-luxury SUV category (the next-generation Acura RDX and all-new Buick Encore), plus we hear big changes are coming to a couple of full-size SUVs. One well-established sport/utility gets a major redo (Pathfinder), too. There will be a lot to see this year -- and there may be some surprises, too.
