At One Stage, Black 2 Was Totally Going To Happen.

The head told Gamespot that the game was shelved after the team lost their "direction".
“I certainly did some preliminary pre-production work on Black 2 once we finished Black, the first three or four months. I moved on quite quickly after that.

“A lot of the guys on the team I’m working with here now carried on with that and did a lot of pre-production for about a year or so on Black [2], before that kind of bit the dust.

“So, I don’t really have personal knowledge about how that all played out. But there seemed to be overall a kind of general lack of direction. I’d be surprised if they managed that again.”</blockquote>

Of course, Stuart Black's now making the spiritual successor to Black in Bodycount, a game that's due on PS3 early next year.
