During their battles, they destroyed Los Angeles (in the form of Mission City), Cairo and Chicago. The city I think they should destroy next during the Transformers battle is New York City. Because New York is a great city they have not destroyed yet, and I think they should destroy it. Think about it. Devastator returning (without his testicles, what was the point of that?) and destroying The Empire State Building, and have the Autobots and Decepticons fight in Times Square. Or maybe it could instead take place in the Financial District in Lower Manhattan and Starscream blows up the Brooklyn Bridge. I'd love that, because New York's landmarks being destroyed by fighting Transformers would make the best action scene in the entire movie series.
