Also...
In regards to the potential trailer, Cody reports that someone he knows involved with Transformers 2 said they are "90% sure" that the trailer will premiere with The Day The Earth Stood Still which comes out December 12th. They also said the trailer was "finished about a month ago".
No idea who CODY is... thought this bit is starting to read a bit like HE TELL ME crud.
