in an interview (in hebrew sorry...) with the head of the N-Gage department at Nokia he said that Dirk Spanner will come out next week:

(The interview actually says Dirk Daker or so but he does say it's a camera driven detective game which sounds the same as Dirk Spanner)

Well, obviously it didn't come out! :)

I think they might have meant that Nokia talked about the game at a public event, which they did in Barcelona recently.

I'm really really looking forward to this game, hopefully it should be a brilliant adventure game.
