Transformers is making a return to the Windy City. Nelson, the admin of Michael Bay's official website, confirmed the rumors with a simple "Yes!" on the website's forum. The news of returning to Chicago isn't much of a surprise since the city gave Michael Bay a lot of liberties during filming (A lot more than many other cities would dream of giving). In fact, Bay actually had some trouble with Los Angeles during filming for Transformers (2007) if memory serves me right. Bay definitely loves Chicago and he is going to bring the Autobots and Decepticons back there this Spring.
