So much hip talk...reminds me of the previous Pope's artificial hip xD Maybe Optimus slipped on the bathtub because he stepped on the soap...and fell down and got a fracture and needed a new hip... Just like the Pope--- xD
Or maybe it wasn't destroyed. It's hard to believe that something as powerful as that is destroyed. When Prime shoots the sun harvestor it might have gone flying the way Galvatron shoots it out of Rodimus'es hand. It may play a role in the third one, and it may be explained then, like the shard in this one.
I seem to remember reading somewhere that Megatron got a hold of the matrix in the end and used it to bring his new army to life (in the comic adaptation maybe?). But in all likelihood, the fate of the matrix in the movie will likely not be known until TF3, and even then the writers might just have forgotten about it and not bring it up again at all.
It actually says on the book "Based on the screenplay" I think it read more like Prime keeps it on his hip like a six-shooter.
Okay so there's three ideas.... Novel: Optimus takes it before destroying the sun harvester Movie: Optimus blows the sun harvester up with the Matrix probably still in it Comic: Megatron obtains it somehow and uses it to make his army Which sounds the most reasonable to you?
The novelization also contains the epilogue where Megatron awakens an army on the Nemesis, so he probably doesn't have it.
"One day an Autobot will rise from our ranks and use the power of the Matrix to light our darkest hour. But he's going to have to buy me dinner first."
