The survey is literally entitled, "Vote for Your New Pac-Man Game!" However, it's a poll for four possible new art directions that the franchise may take in a potential new game, and not exactly a new game or even new game ideas outside of the art.
The art choices say to me that this won't be a traditional Pac-Man game where the little yellow three-quarters circle runs around on a maze board eating pellets and avoiding ghosts. It suggests it will be a new 3D game akin to Pac-Man World is in the works, although the survey asks where you play most of your casual games, and Pac-Man World is not exactly a casual game.
