Transformers 2 - Michigan and a Countdown
Comics2film.com has reported that Michigan has now also been scouted as a possible location for Transformers 2, in addition to Philadelphia and others.
Also, Michael Bay's official website has been updated with a countdown clock counting down the days, hours, minutes and seconds until the movie sequel is released.
A word of advice: the countdown clock is not visible on Internet Explorer 7 for some reason, but can be seen using other web browsers like Firefox.
Thanks to Seibertron.com for pointing all this info out.
