Why do do think they would do that? So they can do a "generic" Indy? So they can re-do their original Raiders Indy under the guise of a TOD Indy? Or because they're sloppy?
Because other than us hardcore geeks, most people think Indy looks the same in every movie.
I wouldn't be surprised at all if this TOD figure came with a complete Raiders look that was representative of all 3 movies and some battle damaged swap out gear for TOD.
