Is it wrong that I think it's both funny and sad that there is only one thread for TF4? lol ... wow.
And I can totally see Unicron being
as I wouldn't put it past something that Michael Bay would do in a movie to up the scale to something even bigger than what came before. Or being the Anti Allspark. That would follow Transformers: Prime from a story standpoint.
I don't support that, mind you. But I can totally see it happening. It ties the Transformers to Earth's history yet again, although I think that's way too close of a tie. Like ... the closest and most ultimate tie there is.
