hey dont know if this posted before, but i think i figured out a lil plot secret. Remember in the teaser trailer when Skorpinok is seen jumping out to attack so unknown bot..well its jetfire..(the stick)..if jetfire is damaged in that battle, then it would lend to other ppl's theories of a damaged Jetfire/ Prime fusion on a side note...if you havent seen the updated movie website do so..looks better than that fallen poster http://i94.photobucket.com/albums/l85/superman516_2006/jet.jpg
I don't think that the theory is wrong. But it would be strange for Scorpy to be the one who seriously damages Jetfire.
