Thought this would interest a few people on here. Quoting from ANN:
I've never really looked into Detective Conan myself, though i do know its fairly popular, but i have seen one or two Lupin III films/OVA's so i may have a look into this if it grabs my interest when more is really known.
This year's ninth issue of Shogakukan's Weekly Shonen Sunday magazine will announce on Wednesday that a "Lupin III vs. Conan" television special will bring together the most famous manga thief and one of the most popular manga detectives. An original story revolving around a treasure will unite the two heroes from Monkey Punch and Gosho Aoyama's manga stories for a "legendary match."
