Stardust Crusaders is rather lengthy (48 episodes, specifically), so Viz and Bang Zoom probably just need time to either finish the dub, or get enough episodes dubbed so Toonami can start airing it without catching up and having to resort to reruns (like what happened with Bleach).

Plus, the first season of Attack on Titan did really well when it first aired, and the second season will probablu do really well too, so they'll want to air that as soon as possible.
