It's hard to tell, Op was ressurected twice, the first time, he was being controlled by the Quintessons to lure the Autobots into a massive explosive trap... My guess is, that they somehow reintergated his spark into the body... or not all of it dispersed...
The 2nd time, he was completely restored by a lone quintesson in order to combat the hate plague, and was given a massive injection of Energon... the Quintesson did warn Skylinx though, that if it failed, Prime would never function again, now I guestimate that it means a spark remnant can only handle so many reanimation attempts before it completely extinguishes.
I think that the second movie really needs to focus on the Robots since most of the human storylines are done.
This movie needs to be an all out war with a good number of Robots on each side. The fight scenes do need to be expanded in range. I think the best look Bay could get on how a large scale Transformer battle should look like is the big battle in the beginning of the animated movie. The Decepticon assault on the Autobot City.
As for the Dinobots I always had an idea on how they should work in the movie. 5 pods are orbiting around space together. Each pod containing a being in stasis picks up on Optimus' transmission and auto locks on it and takes the Pods to Earth.
They crash land in the tar pits of California at night. A small girl who orphaned on the streets is sleeping near it when they crash. The girl wakes up to find 5 large shadows with Dino like outlines staring at her.
Optimus gets a signal saying that certain numbered pods have landed. He gets a serious tone in his voice as he says the Renegades have landed.
As it turns out he is referring to 5 very powerful Cybertronians to decided to remain neutral in the fight. Deemed to powerful to be let lose the transformers lured them into pods that put them asleep.
Well needless to say that the Autobots end up finding them and Grimlock(In Robot Mode) tells Optimus to leave them alone. Sam notices that there is a small girl hiding behind his leg. Grimlok then goes unto tell Optimus what it felt like being exiled against their will just because they chose not to fight. Grinlok says that eh Autobots are not their friends.
Optimus relaizes how wrong he was and leaves them alone as he soon realizes that more pods are crash landing and they are caring Decepticon signals.
He gets together his Autobots some of whom are newly arrived like Ultra Magnus and Kup. Optimus realizes they are out numbered but he still needs to battle them. The middle part of the film focuses on the a big mobilization of different transformers showing up around. Like a massive chess game where Megatron is placing the newly arrived Decpeticons around. Then the battle begins and the Autobots begin to lose.
Megatron finds the Dinobots and begins to smooth talk him unto there side. Gromlok begins to listen and Megatron almost has them joining him until the little girl runs out and tries convince them not to. Megatron calls the little girl a bug and begins to charge up his weapon on her.
Grimlok steps in front and says stop. Megatron begins to talk about how worthless the girl is and the Dinobots need not worry about the Human. Grimlok though replies
"Grimlok no care what you say. Sussy is Grimlok's friend and Grimlok fight for Friend."
Megatron says, "So be it then you will die as well"
Grimlok, "Me Grimlok no think so. Dinobots TRANSFORM."
All of a sudden Grimlok transforms into a T-Rex and opens up his mouth and fires a large energy breath weapon knocking Megatron through a few buildings. One of the Decepticons opens fire and the girl is in the way. Slag though runs in front of the girl and uses and releases an energy shield taking the blast. Sludge lifts his two front feet up and all of a sudden his feet open up to reveal piledriver type devices. Pushing them into the ground a large energy shockwave spreads out knocking the Decepticons down. Snarl swings his body and it releases his tail like a whip. Swoop flies up and comes down and his chest opens up and two gattling like devices pop out and begin to fire missiles.
Well I figured that they robot in the shape of Dinosaurs. I would like for the Dinobots to be more streamlined unlike the Bulky ones of G1. You now kind of look like the Jurassic Park Dinos but Metal instead.
I'm just worried as to how they'll come to be... Fossils? Bones? How the hell are they gonna get their dino forms? Have they been dormant this whole time? I don't know.
He promised us he wouldn't - but welched when he was happy with the fiscal offer, by the looks of it. He then stopped showing off about the formats of release of the movie.
the cartoon didn't really mention the concept of "sparks" at all and i seem to remember scourge opening up his chest cavity to reveal a whole lot of mechanical stuff but no spark.
i've kinda already mentioned this but:
the construticons could have been loyal to devastator and so get shockwave to modify them so that they can combine and then name their combined form devastator in his memory (starscream would bring/call them to earth)
dinobots arrive fresh from combat somewhere off in space; with advanced new scanners acquired in that time (maybe a good chance to introduce wheeljack as the mad scientist here) allowing them to acquire forms based on living tissue. as they land near a museum they decide the dinosaurs would make interesting forms.
and it doesn't really matter if bay is directing or not at the moment; what with the strike action or whatever it is that's happening at paramount
