Beatty does still have the rights to Dick Tracy. What his plans are is anybody's guess.
As recent as last year he won a court battle to retain the rights and was still claiming that he intends to make another movie.
While being the producer of a Dick Tracy movie would seem to make sense, his intent seems to be to play the character once again.
He even went as far as to make "The Dick Tracy Special" in 2010 in order to retain the rights.
It featured him as Tracy being interviewed by Leonard Maltin and showed clips from all the Dick Tracy films, including his.
