A new Yu-Gi-Oh! anime has been announced as part of the 20th-anniversary celebration for the anime series.
2020 is considered to be the 20th anniversary for the Yu-Gi-Oh! anime series, because the current license holders want everyone to forget the original Yu-Gi-Oh! anime that was developed by Toei in 1998. The second iteration of the anime debuted in the year 2000 and was called Yu-Gi-Oh! Duel Monsters in Japan. It was this series that was localized internationally and would debut in North America in 2001 under the name of Yu-Gi-Oh!.
It was revealed by Konami during a livestream that was held as part of Jump Victory Carnival 2019, that a new Yu-Gi-Oh! series was in development and would be released in 2020. There are currently no details concerning the content of the series, but there was an interesting quote made in the announcement video that might hint as to the premise of the series. According to the Anime News Network, the text in the announcement claims that "The history of the Yu-Gi-Oh! anime series will change." The reference to the history of the series might mean that some older characters in the series might be returning....
It's possible that the new series could be a Dragon Ball Z Kai-style remake of the original Yu-Gi-Oh! anime series. The visuals of the Yu-Gi-Oh! anime have aged poorly in this era of high definition screens and there are several filler arcs that could do with pruning. There are still a lot of fans who adore the original cast and they would be on board to see the return of Yugi, Joey, and Kaiba, especially as the series is due for a Pokémon-style resurgence of interest from older fans who are nostalgic for the original series.
There is already a Yu-Gi-Oh! spinoff anime being broadcast in Japan called Yu-Gi-Oh! VRAINS, which debuted in 2017. Yu-Gi-Oh! VRAINS involves duels taking place in virtual reality and is centered around the new Link Summoning mechanic from the card game. It's unclear how the new anime will influence the run of Yu-Gi-Oh! VRAINS.
The new Yu-Gi-Oh! anime series will debut in 2020.
