The previews of the next arc are the filler saga. The green haired Kaiba kid, he wasn't in the manga. It happens over like 25 episodes where they go to some virtual world and there are those 5 evil corporate guys. I never watched it. Then they go back and finish the Battle City arc as the second half of season 3.
Then the next season is all filler with the motorcycle guys. Then Season 5 is the first half is a separate tournament with that pink haired guy… then the second half is the final canon arc which is the Memory World arc.
