Coming near the mid of the month, there's going to be a new Legendary Duelist! With the only hint being given is that we have to "Want some new cards? You're gonna have to beat me!"
Since it is not stated that it's going to be an unlockable character, it might be safe to assume that it's going to be similar to event like Yugi Muto appearance event.
An important character in the show, Mokuba Kaiba is Seto Kaiba's younger brother. Character image files can be seen by datamining the game, showing that it is possible that he might be an unlockable character, or appearing as a duelist through events.
The June event announcement in Japanese sounds really same to the tone of Mokuba in Manga/Anime. For other possible characters, check the link below.
