I've literally just said this in another thread, but it's very relevant in here too.
It was even on the news on TV that Matt admitted they're running out of ideas, and wants to wind down the show. The voice actors are signed for another 2 seasons, that would make 15 in total. After that, looks like Fox get payback
I think it's good news; The Simpsons is really going down in quality and becoming a parody of itself. Unfortunately I doubt the fact that the end's in sight will have any affect on Futurama.
