The quotations on "knew" imply "you assumed", rather than actual knowing. Upon finding out that Megatron was the tanker truck, I "KNEW" that we'd see Megatron and Optimus collide head first in alt-form for one of their battles in the movie. I also "knew" that Sentinel Prime would die at the end, though I thought by sacrificing himself to stopping Shockwave and his evil machinations (whatever evil plot device of doom it would be). I also "knew" that Shockwave's personality was going to damn-near replicate G1's Shockwave. God damn, fun times with the earlier speculation.
