Namco Bandai has announced that this E3 will see "the worldwide premiere of the newest Pac-Man project". An event invitation sent to members of the press says attendees should "prepare to witness the next evolution" of Pac-Man and promises playable versions of "unreleased titles on console, mobile, arcade, and more".
It's currently unclear whether the invite refers to the four-player Pac-Man Battle Royale that was recently spotted at Amusement Expo 2010 or some entirely new Pac-Man game. A Namco representative refused to comment on the matter.
The event is scheduled for the evening of 15th June.
