Turns out it isn’t just the human cast of the “Transformers” franchise that’s getting refreshed. It looks like the robots are also being replaced by cheaper parts.

TFW2005 has scored word directly from Hasbro that toy sales from the third film were down because of same characters in all three movies.

As a result, “Transformers 4 will have a new cast of [robot] characters and it will be a story revolving around these new characters.”

Ehren Kruger (“Transformers: Dark of the Moon”) is writing the script for the Michael Bay-directed fourth film which hits cinemas June 27th, 2014.
