We've known since August, but now It's official. At a meeting today, GM announced to their network of Buick dealers the new mid-size sport sedan from Buick will be none other than the Regal.

The North American Buick Regal was replaced in 2005 by the Buick LaCrosse, built using the same W platform. The final 2004 Buick Regal rolled off the assembly line on June 1, 2004. Now it would appear it'll be back and as we told you back in August when Lutz let slip this tasty piece of news to Scott Burgess of The Detroit News, it'll be the same as was launched in China in November 2008 based on the Opel Insignia. More details as we get them. [Twitter]
