How much of a time gap was there between season 1 and season 2? Lemme look..
Episode 10 of season 1 air date: January 13th, 2008
Episode 1 of season 2 air date: February 12, 2009
A year and a month gap! So, it's highly possible... with this season ending april 16th... that we might not get anything until, like, May of 2010! I imagine it takes a loooooong time to do an episode. Not just the animation -- which, while still being done with computers, is infinitely more complex to animate than something like Aqua Teen I'd imagine -- but the scripts. Another underrated part of the show is definitely the complex sound design and voicing; really, the whole show is a total package of entertainment, and there is so much work that goes into all of it, I imagine. So, yeah.
We'll see....
