Chris Hewitt of Empire Magazine have published a small article on the Empireonline website regarding a quote that Transformers star Josh Duhamel gave them when they bumped into him on the set of When In Rome last week. The quote he gave them was in relation to their question regarding what was the difference for his character, Lennox, in Transformers: Revenge of the Fallen, compared to the original Transformers Movie.  Josh's reply was"“I guess who he’s working with is probably the biggest change,” said Duhamel, before adding once more, presumably for emphasis. “Who he’s working with.”".  Empire are reading into this that the Autobobts and Decepticons will be teaming up to face a more powerful enemy, in their minds that is The Fallen, though when you read the Transformers 2 Game summary, it could also be a powered up Starscream, perhaps using a fragment of the Allspark in an "Underbase" style powerup.  Of course, this is all speculation at this stage, but time will tell.
