I have no idea about the USA version. Suitcases? What were they thinking?!
To us in the USA, I don't think most of us even knew they weren't briefcases in the original.
Actually, the Dutch version of the show (the original) does in fact use briefcases. The models opening the cases, on the other hand... I mean, just bringing them out is fine, but removing the only reason to watch the briefcase game as a stand-alone show was just stupid.
