It's been spoken about for quite some time but, truthfully, we never really ever thought it was going to happen, or even if it was a good idea in the first place, for that matter. 

How could it possibly work? Both logistically (where the hell even is Springfield?) and as a comic vessel for both shows. Surely it just can't work?

Well, after watching these five minutes of animated gold following their premiere at this weekend's Comic-Con, we think we might have been a bit wrong on that one because it looks awesome.
