TheLastPrime, a member of the TFW2005 boards, has some type of connection related to the making of Transformers movies and has provided tons of insider info for Dark of the Moon months before official announcements. News tips included the Wreckers, a scene in space, and Simmons becoming a rich author. He's back with some Transformers 4 news now and he says that they will be filming in Detroit (which has already been rumored) and Houston, Texas. This is unconfirmed info, but this guy has proven to be a pretty reliable source. Check back for any official announcements right here!
