Yup, even though Namco denied it before, PacMan was announced at the Nintendo Round table conference at E3 and was announced publicly afterwards.
He’s pretty much as I thought he would be in the game. But he can summon sprites from other Namco games like Galaxian, Xevious, Bosconian, Mappy and the PacMan ghosts.
On the WiiU, PacMan’s level is a scrolling PacLand stage.
On the 3DS, PacMac’s level is a procedurally generated PacMac maze.
