If they’ve been saving some info for later, this is the perfect venue.

Konami will be holding an in-person event at the venue for JUMP Festa, as well as an online event. People attending at the in-person event at Makuhari Messe will be able to experience Yu-Gi-Oh! Master Duel and Yu-Gi-Oh! Cross Duel early, as well as Rush Duel (maybe with some new cards?).

Additionally, you can experience Duels using oversized cards!

As a summary, at the in-person event you can buy OCG and Rush Duel goods, play test Master Duel, Cross Duel and Saikyou Battle Royale, and there will also be an online show featuring all of the card game related products (OCG, Rush Duel/Saikyou Battle Royale, Duel Links, Master Duel and Cross Duel).

Further information might be revealed in the following weeks before the event.
