In JAEPO 2020, Konami unveiled two new rhythm arcade titles that were never released:

• "NEW pop'n music Welcome to Wonderland!" was created as a reboot to the long standing "pop'n music" series. The game used a different arcade cabinet with smaller buttons and a touch panel meant for new slide notes. Aesthetically, the game also utilized 3D models for the characters as opposed to 2D sprites. Both licensed songs exclusive to this cabinet, "Phantom Joke" and "少年よ我に帰れ", were added to "pop'n music peace" on August 3rd, 2020.

• "jubeat (2020)" was also meant to be a reboot, this time to the identically-named "jubeat" series. Unlike "Welcome to Wonderland", the gameplay remained identical between it and previous entries. The arcade cabinet itself was roughly 1.2X the size of previous iterations and ran at 60 fps, as opposed to 30fps. The cabinets also supported music videos and would have come in several colors. In 2021, a mobile version of jubeat released utilizing similar aesthetics to this cancelled version. 2022 saw the release of a new iteration, "jubeat Ave.", which utilized the previous arcade technology.
