I think this saga is trying not to be so spiritual or supernatural in a sense. So Unicron will simply be a massive Transformer who wrecks planets and consumes the resorces. I don't think he'll be too much of a godlike character other than his size. And I'd imagine Unicron wouldn't take a planet sized, humanoid form either. I think we'll see his robot form either as a smaller bot. Or maybe concealed within the 'DEATHSTAR' like shape we all love. Like a sort of brain thing. Anyway, I don't think PRIMUS will appear in this saga, other than stories. To be honest. I don't think I want to see PRIMUS in this saga. I think the GOD-LIKE story line ruins the TF saga. PRIMUS worked for ARMADA but I don't think he'll b good for TFP. Still that's my opinion. The writers have to consider the majority of what TF fans want. And so far I think they're doing a great job.
