Quoted from TigerLaw:
With the exception of Batman 66, Stern has never really shown an interest in anniversary dates. Matrix would have been a superb theme back when the trilogy was hot, perhaps the new movie in development will breath life back into the franchise.
I believe if Williams/Bally had survived a few more years until 2002 or 2003, we probably would have seen an awesome Matrix pinball machine. Let's hope the modern manufacturers will make one!
