We're in the heart of General Motors' downtown Detroit headquarters for a press conference tied to the 100th anniversary of Chevrolet, and Chris Perry, the brand's Vice President of Global Marketing and Strategy, has just confirmed a new TrailBlazer SUV. To be based on the company's new global mid-size Colorado pickup, the vehicle will be unveiled November 10 at the Dubai Motor Show.

Chevrolet officials have not yet offered word on where this vehicle will be built or in which markets it will be available, but given that the Colorado has recently been confirmed for the U.S., we wouldn't be surprised to see a new TrailBlazer once again plying America's roads.

Earlier this year, we received spy photos and a video of a new mid-size General Motors SUV testing near the automaker's headquarters, meaning development of the Colorado-based TrailBlazer could already be well under way.

More details as they become available.

UPDATE: General Motors has released an official teaser image (above) as well as a press release, available after the jump. The automaker confirms that the 2013 TrailBlazer will first go on sale in Thailand beginning in early 2012.
