Transformers producer Don Murphy has explained on his message board why we haven’t heard any official Transformers 2 news:
For those of you most anxious about TRANSFORMERS 2, the silence you hear is primarily because people are fretting about a presumed strike in June 2008. Will it happen? I don’t know- does the public care about strikes anymore in this day and age? What do rich people have to strike about anyway? I don’t have any side here (you hear about the writers and the Producers but that actually means the STUDIOS) I just think stopping work is kind of pointless. But since no one wants to be filming IF a strike happens, everything needs to be done filming by the end of May 2008. So this is affecting the lack of news about Transformers 2 at least for now. Stay tuned.
