So as far as the Disney video games besides Disney Infinity and Ducktales Remastered, there were several others represented at E3.

Phineas and Ferb: Quest for Cool Stuff is a platformer game in which you can play as either Phineas and Ferb, hunting for artifacts to populate their Museum of Cool, or you can play as Agent P, out to foil the evil plans of Dr. Doofenshmirtz. [Multiple platforms]

Kingdom Hearts III was announced in development by Square Enix. Despite the name, this will be the eighth installment of the Kingdom Hearts series–an action role-playing game which combines characters from the worlds of Disney and Final Fantasy to wield keyblades and battle the Heartless. [Playstation 4, XBox One]

Castle of Illusion Starring Mickey Mouse is a side-scrolling platformer which will be remade for release later this year. Although the 3-D graphics will certainly be an update from the original 16-bit version, presumably the storyline of Mickey entering the Castle of Illusion to save Minnie will not. [Playstation 3, XBox 360, PC]

Possibly the game with the most confusing trailer was announced shortly before E3–Fantasia: Music Evolved. Billed as a successor to the movie Fantasia, it is a motion-controlled music rhythm game in which the player follows gesture prompts to gain points/energy that are subsequently used to open up and give life to different virtual environments. Oddly enough, there has so far been no indication that any Disney music or characters will be used–the Fantasia tie-in seems to be the manner in which the player conducts “molecular magic” like Sorcerer Mickey. My favorite part? Jazz clams! [XBox One, XBox 360]

…and, oh yes…
