Electronic Entertainment Expo. It's where enterprises gather every year to show to the imprense in conferences their projects to be released. It can be launched months later (commonly on Xmas) or on the next year.
Missed out on a chance to play Travel in Time which was at the Eurogamer expo in Earl's Court, London today due to strikes on the London Underground. MCM expo hasn't confirmed if Ubi will have the game there as well but I'm gonna wait and see.
