If you are a developer, take your time with the game. You will not get laid off with another year added if you just take your time.
If you are a big publisher and you already spend $300 million on a game after a 5 year development cycle, you can't afford to let people go with another year added to the games development.
And we all know the famous Kojima quote "a delayed game is eventually good, but a rushed game is forever bad"
