Just saw it posted on Xbox360achievements.org here http://www.xbox360achievements.org/news-2495-Game-Added--The-Simpsons-Arcade.html meaning it will come eventually, especially since there is already an achievement list located here http://www.xbox360achievements.org/game/the-simpsons-arcade/achievements/. No actual release date has been added, but at least you know we can relive those times of filling the machine up with quarters. Battletoads next anyone?
