Since this seems to be dueling sources, anything I added to their posts for clarity are in [ ]. I tried to suss out the two voices the best I could but probably have a few wrong. As a result you will see Anonymous  and Anonymous . Ignore the spelling errors and the like mostly because most comments tend to be informal and not proofread so difficult to draw any conclusions based on that alone. For now all this remains as rumor/fan speculation with usually caveats that apply. I have no clue if any of this is true. Its plausible, it fits some of the alterations that Bay likes to make to Transformers. Really its impossible to judge the info as we have no real information about the movie beyond the basics. Thanks to BennettPrime for the heads-up.
Optimus Prime, Bumblebee, Ratchet, Hound, Drift (black and blue Bugatti Grand Sport Vitesse), Sunstreaker (green C7 Corvette Stingray), Slag, Grimlock (T-Rex alt mode), Vector Prime (codenamed Ultra Magnus or Mags), Sideswipe, Topspin (blue Wrecker), Roadbuster (green Wrecker), Leadfoot (red Wrecker), Sea Spray, Rodimus (red Pagani Huayra), Prowl (dark grey Lamborghini Aventador), Cliffjumper (purple and white Sonic RS Rally)
Overkill, Lockdown (black Rally Fighter), Thunder (?), Menasor, "death vector prime", but no Stunticons
- The black and dark grey 2014 Freightliner Argosy is alt mode of Vector Prime or Menasor
- 4 Autobots killed; Ratchet early in film, Drift and Topspin by Overkill, Vector Prime by Lockdown
- Grimlock created from Ratchet's spark, smart but sounds like a caveman voice
- Dinobots will be "actual dinosaurs like Jurassic Park"
- Stanley Tucci plays a "scientist character" with knowledge on time travel
- Energon Sword given to Mark Wahlberg's character by Vector Prime before Vector is killed by Lockdown
- One of them says Galvatron is the big bad, another says he isn't in the movie
- Face is described by Anon  as Leadfoot and Grimlock by Anon 
- Main bad guy (not Megatron, maybe Galvatron) outnumbers the Autobots 20 to 1
- Unicron is mentioned several times in the script

The new black truck is Menasor. There will not be Stunticons in this movie.
Dinobots, will be actual dinosaurs like Jurassic Park, but with robot modes.
Grimlock, will be a T-REX with caveman voice

Yes the green corvette is Sunstreaker. The pagani is hot rod and the lamborghini is Prowl
The face [here] that was shown is Leadfoot and he is talking to the Scientist character about time traveling. Vector Prime gives his Energon Sword to Mark Wahlberg before he gets killed by Lockdown who is one of the Rally Fighters.

Face is grimlock but the rest is very close!

I can confirm some, but not all of this is correct. He doesnt have the characters correct. He never says who the Sonic is, The lamborghini is not sideswipe and the pagani is not drift. The gray cab over is Ultra Magnus, The pagani is rodimus since they can not use the hot rod name, the Lamborghi is prowl, the sonic is cliffjumper, The one he got right is the green corvette, which is sunstreaker. Drift is the bugatti

@ u sir have 2 correct, no hot rod no prowl! Ultra magnus hmmm u wont believe who he is. Cue the jaw drop when u see him! What do u know about mags and " megatron"

@ ok this is it though! I give u quotes u dont believe! Megatron is alive but if u want the main bad guy and his army that outnumbers autobots 20 to one, all u got to do is look to the planets! Is that big enough!

I know it's hard to believe anyone these days, but form what I've been told by sources close to production these are the names of the vehicles. All the vehicles that have been shown are autobots. There will be decepticons in the film, but they will be completely cgi. Galvatron is the main decepticon villain. The Dinobots are neutral for most of the movie, but join the autobots in the last fight. They to will be all cgi. As for the vehicles, The sonic rs is cliffjumper. The lamborghini aventador is prowl. The corvette is sunstreaker. The bugatti grand sport vitesse is drift. The freightliner is ultra Magnus. The pagani huayra is rodimus. Of course we all know the other 3. The wreckers will make an appearance. Sideswipe, sink, and ratchet will as well but only in robot mode.
