Sorry bout the delay in posts lately but Man do I got some Spoilers to announce For ROTF.
First is first, None of these are confirmed that I'm aware of except the Fallen news. Okay first things first. The first transformers ROTF trailer will premier during the super bowl. Jetfire was a Decepticon but later changes to the autobots alliance. The twins will be able to combine or powerlinx as seen in transformers energon They also fight amongst themselves.... alot. There is a little blue remote control car thats name is either Wheels or Wheelie who drives underneath jetfire in the museum thus learning Jetfire is or was a decepticon. Okay time for the confirmed facts Arcee is to be a combiner in the form of 3 motorcycles, 1 pink, 1 purple, and 1 blue she is also supposed to have hologram riders. The main enemy in ROTF is Fallen, or the fallen, Megatron may not be in the movie. Bumblebee gets a new alternate form. Soundwave is going to be a pickup truck with a cybertronian form of a satellite. Fallen was imprisoned by the Egyptians after being worshipped as a god. Fallen was one of the first transformers that landed on earth. Fallen has been trapped inside the pyramid asleep for thousands of years. These are not confirmed yet but The Autobots and US Military will team up to track down rogue Decepticons. Springer will be one of those Autobots. A scene is referred to where Alice reveals a nasty secret, a tail with a hypodermic needle that emerges from her back. Devastator resembles a gorilla. There is some conflict over whether Megatron will show up or not. As per Michael Bay's statement, the first source mentions Megatron will not show up. However, the source for the Superbowl trailer mentions not only will Megatron be in the movie, but his relationship with Starscream will be far more prominent this time around.
