Just Dance Unlimited/Beta Elements

Graphics

 * As seen at E3, the songs weren't listed in alphabetical order.
 * In a beta screenshot, it can be seen that the service was supposed to have a "Favorites" section, similar to Just Dance Now. Additionally, Dark Horse was also seen in the Katy Perry playlist, despite not being featured in it in the final game.

Dancers and Gameplays

 * Cheerleader (Felix Jaehn Remix)'s preview shows placeholder pictogram colors. In the final version, the pictograms are colored Dark Pink, Light Pink, Green and Blue.
 * Additionally, the Gold Move pictograms did not have a gold aura around them.
 * The coaches had different colour palettes as well: they are shown on the Just Dance Unlimited promotional logo.


 * Am I Wrong's coach was originally going to have a blue outline instead of a yellow one, as seen on the song's square and coach selection image.

Songs

 * The glove color layout from Yō-kai Taisō Dai-Ni, which is Yellow/Red, was originally meant to be used in Yō-kai Taisō Dai-ichi as well. However, the glove color layout in the latter was changed to Blue/Yellow.
 * P4's glove from Geragerapō No Uta was originally light blue instead of orange. A trace of this can be seen in the routine, as P4's glove will sometimes glitch to light blue.
 * The background of Jinsei Dramatic was detailed differently; there were less Yokai appearing in the background, the sun during the sunset scene was shining much more brighter, the lighting in the daytime scene was less realistic, and the USA flag-theme animations weren't supposed to appear, and the coaches were supposed to have a faded outline instead of a outline that's in full opacity. Also, Ottamagator was supposed to make a appearance in the background. However, in the final routine, he is replaced by USApyon.
 * P3 and P4's glove from Uchū Dance! was originally colored different, as P3's glove was red while P4's glove was yellow. The glove colors was later changed to Yellow/Purple in the final version.

Gameplay

 * As seen in a screenshot, the original stars were originally going to be used instead of Jibanyan's head.
