Tonight at an event for Zone of the Enders, game designer Hideo Kojima and his studios Kojima Productions announced that they were working on a new Z.O.E. project that currently has the working title of "Enders Project".
Details are scant, but the first concept images for the game were shown.
DISCUSSION
It's probably not Zone of the Enders 3. Considering the title he gave it, it's probably an anime, a radio drama or something we will never see in the US. Kojima already pulled this stunt with Snatcher a few years ago, teasing and announcing a new "Snatcher project" that ended up being nothing more than a pointless radio drama CD.
If it was a game, he would've said it was a game. Don't get your hopes up, people.
