I will binge watch the entirety of part 3 and nothing less.Stardust Crusaders will take a break around September until next year when they arrive at Egypt: http://www.crunchyroll.com/anime-ne...os-bizarre-adventure-stardust-crusaders-anime
If you're planning on waiting until the anime is done to binge watch, I suggest doing it when they're on break. It's gonna be a while.
