AllSpark Experiment Secret Video - Bay Says Transformers 3 Goes Deeper

The 2nd movie is barely over and Michael Bay is already talking about what's in store fro Transformers 3. From a secret clip on the Transformers Blu-ray disc edition. Bay give us some of his thoughts on where he wants to go with the thrid installment citing the moves were grand enough that his desire is to go "sideways" deeper into the Transformers movie backstory and give us something darker and more emotional. From TFLAMB:

In the video, Bay suggests he is going to try to go "sideways" rather than bigger with more research into Transformers lore (and image of animated Unicron is shown). His desire is for something that isn't just action but something darker and more emotional. The video was likely recorded before he committed to getting TF3 out for summer 2011 and really its way to early to draw any definitive conclusions from the video as likely the film is still in the spitballing phase to see what sticks. The video is below or click here which also has the solution to unlock the video. Thanks for Katie for the link.

So what do you think? Is this more Bay talkin' shit? Can Mr Bay do the story justice? Is it too late to repair what many see as very week plot line and fragmented Transformers canon? And Unicron, what's he going to do to our dreaded planet eater? Is nothing sacred?
