The callsheet that mentioned they split in two the first time around with arcee's scenes, listed them as a decepticon that splits in half. (Jetfire/Arcee Callsheets for her chase scene, and sam's discovery of jetfire.)
A sheet released later that I never saw personally, allegedly refered to them by name as autobots. And everyone since has speculated they are sunstreaker and sideswipe, inspite of the first callsheet leaked listing it as a decepticon. So no clue why that misinformation took fact(cept for those that don't know how to read call sheets). This at least clarifies what we should know already, that the ice cream truck is indeed a decepticon.
My personal opinion on the ICT is it's a Soundwave companion set or the Reflector Unit.
Something espionage related. Since they run from arcee, it has never made sense to me why they would run from a fellow autobot.
Though this does leave the potential for the other 2 bikes to be bots, but who knows. That could work just as well as a joke until they rescan. Then again it also works for the chase scene to have multiple arcees, so she can split up and tail them.
As for the rest, this goes hand in hand with what orci had said about my questions in his thread. Though I'm curious how they'll interweave the glyph stuff in. Maybe now sam can read them? I'm just glad those 15 questions will be answered in the movie, though after
ROTF I would like to see the writer's perspective on the '2001: a space odyssey' nod.
And we already knew Radiation from something unearthly was potentially causing Sam issues. Whether it was the allspark, megatron interaction, or the glasses. Maybe even the years of exposure to BB mixed with the rest.
Orci hinted at that already in his questions thread by use of a 'it'll be answered in the next movie', and the recently leaked fan footage helps maintain that truth.
