According to The Wall Street Journal
, General Motors will be ceasing production of the GMC Topkick by the end of July. Unable to find a buyer for their medium-duty trucks, General Motors decided to end production on the GMC Topkick and Chevrolet Kodiak in its effort to streamline its operations. The end of the GMC Topkick presents an issue for future Transformers movies beyond Transformers: Revenge of the Fallen
