Sam did not die n Dark of the Moon
yes sentinel prime shoots him in the back and head
Megatron and sentinal prime and all the decepticons get spacebridged back to cybertron
That is unknown. It is rummored the Ratchet may bring him back to life in Transformers Dark of the Moon, but we will have to wait and see.
Megatron still is alive in Transformers 2 so he will be back with Starscream and more Decepticons
think so cause it said Rachet took a peice of the Allspark and used it on Jazz
jazz is coming back to life because people been wanting him back and the michal bay wantit him back to *Sadly our dear friend Jazz hath not returned in Transformers 3: Dark Of The Moon. But there is another Autobot that may be confused with Jazz. Sideswipe is the same silver color, as Jazz, and a sports car, also like Jazz. As far as I am aware Jazz will not be in any new Transformers movies, if there are even any new movies.*
Actually no. Because we cannot see the back side of the moon. But it is not always in dark. Sun can shine on it too
yes
No, Optimus Prime ripped his face off and smashed his spark
There is a HUGE possibility then again there isn't. The press has word that Shia Lebouf may not be coming back, but is Transformers: Dark of the Moon is a BiG money-making turn out why wouldn't he? Also, Micheal Bay says he wants to slow down for a moment and see the turn out of Transformers 3 then he will go on to decide whether or not to continue with the Transformers sequel. BTW : Transformers 3 is a GREAT movie GOT to see it because I would loveee to have another twist and turn to it in the fourth one soo it is up to us people lets get a move on ! :D
Iapetus has. Nobody knows why there is a dark side but it is probably dust from the moon Phoebe.
Yes absolutely. The moon is at the back of the earth so the earth becomes dark.
