It comes to our attention that Bandai Namco Entertainment Europe had registered the trademark Taiko no Tatsujin: Pop Tap Beat in Europe. This is likely a localized title for Taiko no Tatsujin Plus: Shinkyoku Tori Houdai!, but we will still wait for any confirmation from Bandai Namco, likely at Gamescom in Germany.
Taiko Team's official Twitter had announced that the Undertale Pack DLC, which contains 3 tracks from the video game Undertale, will be coming to both Taiko no Tatsujin: Drum 'n' Fun! and Taiko no Tatsujin: Drum Session! on October 10 and October 24 respectively in Japan and Asia regions. The pack will likely be made available for the US and EU copies of the games at later date.
