Ion Storm is gone. Spector's working at his own new studio. He's not gonna have anything to do with this game. ):
I hope they bring back the depth of the first game, too. Ion went way overboard with "streamlining" the game to make it more accessible with IW. While I do think that some of the changes made in IW were at least with good intent, the world was so devoid of detail compared to the first game that I sometimes wonder if maybe they were rushed more than they've let on in any of the interviews I've read.
