According to the latest GG Q&A, this piece is expected to show up later this year.
"GGC: Any Update on the Indy Dr. Henry and Junior on motorcycle?
GG LTD: This is a very complex piece, and we want to make sure we execute it perfectly. We anticipate it hitting shelves by the end of this year."
And here are tidbits of the other Indy products:
"GGC: Short Round has recently been announced as a EE Exclusive, what is going on with the card holder, paper clip holder and all the other Indy items we have seen?
GG LTD: All of the Indiana Jones desk accessories are shipping now. Collectors can look for them around mid-end of February at their local retailer."
No mention of any new product. Seems that once what has been announced is shipped, the Indy line appears to be done.
