Continuity Questions and Discussion for TF3.

Ok, some things I'd like to discuss.
Optimus basically stated he is the Fallens brother, but didn't all the brothers freeze themselves around the Matrix? What does this mean, does this mean that Prime originated from the same source as the fallen?
Does it mean that non-primes originate from a different source?
Then in TF1 Optimus said Megatron was his Brother, does that mean Megatron is a Prime as well?
Next thing is is that they showed protoforms and stated they need Energon to keep them going. I' m sure Prime would agree that keeping his own kind going is important. Should he address this in TF3?
What is creating these protoforms?
I think the combo of the origination of Optimus, his relation to the fallen and Megatron, could be an intro to a character like Unicron.
