I got a newsletter by Kazé Germany stating that the Lupin vs Conan movie is going to be shown in German cinemas on August 27.
Here's a dubbed trailer. Lupin isn't really a big thing in Germany and this was probably brought over because of the Conan connection, but it's still pretty nice. As far as I know, only Cagliostro, the 2014 live action, and a few of the 90s TV specials have ever gotten a release in Germany.
