i work at a local theater and we watched friday the 13th (alright movie) but the new trailer for TF is fuckinnn sickkkk. they used a lot of the same scenes, but a couple new ones. i cant tell u wut i saw because i couldnt pick up that much, but u do see the one of the constructicons transforming (the rh400). also there is a great shot of the pyramids right in the beginning, and im not sure if it was fallen or megatron but there is a full shot of one of them, im leaning more towards the side of megatron but he had a pointy head lik fallen, not sure tho. You also get a better shot of the audi r8 smashing threw the building and a better glimpse of all three parts of arcee coming threw chasing after him. thats all i can remember about the trailer. sorry for lack of detail thats the best i can rememberIt sounds like Michael Bay takes the word "teaser" seriousily. Exactly when that trailer will show up online (for overseas fans) is unknown but hopefully sometime in the next few days. Also note to movie goers that theatres are not required to attach the trailer to the movie so no guarantees that going to see the movie means you will see the trailer. Thanks to Tyler for his description.
Update:Another description, this one confirming the appearance of Scorpinok. Thanks to Boo for the info.
I can confirm that Scorpinok is also in the trailer in a shot that looks to contain the Audi in the desert. Also there is a closeup where Sam pulls apart what appears to be a small robot beatle. The RH-400 transformation looks to take place during the Bethlehem Steel scenes and all 3 bikes appear to have a unicycle type robot mode. The protoforms take out a number of buildings and the entire ship fleet, which is shown sinking in an under water shot. I'll see if I can find time to watch again and hit you with anything else I notice.
