Correct me if I'm wrong, but how so? Doesn't everything that's not a figure (BP's, Mid sized ships, OT exclusives) have the same design with the clone troopers on? I know that the At-Te and Turbo Tank come with CW figures, but that still doesn't say to me that they're CW specific.
Well, one is clearly marked "The Legacy Collection" and one is marked "The Clone Wars". It's right on the front of the box above the photo and below the item name. The box size and coloring are very similar though.
