Producer Lorenzo di Bonaventura has confirmed the appearance of the fan favourite Autobots in the upcoming film.
"I can't disclose the specifics, but you can be sure that the addition of the Dinobots will be cause for excitement," he told Beijing News (via TFW 2005).
He added that the film would feature "the world's coolest, most exciting cars", including some Chinese models.
Unlike Iron Man 3, which received a highly-ridiculed Chinese cut after filming in the country, Bonaventura said that there would only be one, global version of Transformers 4.
Mark Wahlberg, Jack Reynor, Nicola Peltz, Stanley Tucci, Kelsey Grammer, Sophia Myles, Li Bingbing, Titus Welliver, TJ Miller and Han Geng will star in the film, which will be director Michael Bay's last outing on the franchise.
Transformers 4 will open in cinemas on June 27, 2014.
