That's just not true. Yeah the timeline may not be set in stone for things that are far enough in the future, but short term deadlines are always necessary and need to be followed. You either have a goal or you are just aimlessly wandering. Whatever, this has been discussed to death. More developers doesn't mean the game is getting made any faster. If anything, two or three architects can lay the foundation of the entire game themselves in a relatively short time. Then it's mostly about creating enough content.
