Today, Bay unveiled a swanky new Transforming vehicle, the 2013 Lamborghini Aventador LP-700-4 Coupe. Since this Aventador is black, and villains usually wear black stuff, we're going to go out on a limb and say that this will likely be a Deceptacon. (You can scroll through the site and see other potential Autobots and Deceptacons, all managing to look both showroom and battlefield ready..)
Among the human actors scheduled appear in the fourth "Transformers" film are Mark Wahlberg, Jack Reynor, Nicola Peltz, Stanley Tucci, Kelsey Grammer, Sophia Miles, Li Bingbing, and T.J. Miller.
"Transformers 4," which hasn't begun principle photography, will be out on June 27th, 2014. Mount up!
