It was supposed to have been back in 2007. When Sam Fisher had that hobo look with a full beard, shaggy hair, and running from the government. Sam's look reminded me a lot of Robert Redford from Jeremiah Johnson, and again, with the running from the government plot Three Days of the Condor. Anyways, it was delayed.
In 2006, I remember the game title was leaked with images; along with other games.
Nothing has been heard about this game until last issue of Game Informer. Now the current issue reads of its delay, along with other games.
Game Informer is my sources for this information.
As for Bioshock 2. That does, indeed, stink to see it delayed. I really enjoyed the first one and really hope the second one delivers and provides just as much entertainment as the first did, and still does! I can wait for this game, too!
So, that is that regarding Splinter Cell: Conviction
