How much mineable content is there really?

I'm new to the game and to the show. I've grown to love them both in a very short amount of time. My one worry is how much content is there really in Futurama that this game and it's creators can mine?

I understand the show only last 10 seasons and a few full length feature films. However, games like Family Guy and The Simpsons are continuously having new content created due to continuing to make episodes for each show.

Ultimately, what I'm trying to ask is simple: To all the Futurama-holics and Futurama-addicts how much content is there?

How many characters? Buildings? Planets? Aliens? Creatures?

Will it be easy for TinyCo to run out of content?
