Arthur 3000 was an upcoming story arc contained in Elwood. It would feature R4 and 3W, Arthur's future great-grandchildren in the year 3000. These characters were first seen in the Arthur episode, Background Blues. It would've start in late Volume 5 or early Volume 6. It was announced at Elwoodstock I, but then Samuel Anderson said that "it probably won't happened, and if it does, it's in the far future".
