Last night Michael Bay confirmed that the military truck which was revealed as an Autobot in recent on-set images will indeed be called Hound. The bio on Mr Bays's website read as "The always rugged and reliable Hound, one of the Family of Medium Tactical Vehicles from Oshkosh Defense. High resolution". We'd expect Hasbro to release a "Roadbuster" style recolour either as Roadbuster or as "Roadbuster Bulkhead" when a toy is eventually released.
In releated news, Fox Detroit have posted a video, which can be viewed below, regarding the recent Transformers 4 casting call which took place in Michigan. The report states that Michael Bay will be stepping up his filming within the area including using the location to shoot parts of the story which will be set within Hong Kong.
