I like the shifting in this trailer its more realisticly done than in the movies, I just hope for a movie reboot, with all the characters the way they should look, Ratchet as a white gm ambulance, Megatron as the walther P38, Star Scream as the F-15, Wheeljack as the rally car, Devastator as the yellow behemoth , not the MIB cockroach as in TF2, Shockwave as the galactic hand phaser, why was mass-shifting such a problem or Megatron and Shockwave as a gun, that's how we know them from the cartoons anyway, such a shame to even change the original concept...
Anyway I like this trailer also, hoping for a movie reboot ....Chris Nolan should do it, wonder how he would make the transformers seem believable.
