Comedy Central will be producing another 26 episodes of Futurama, due out mid 2010.  http://www.tvweek.com/blogs/tvbizwire/2009/06/the-futurama-is-now-comedy-cen.php

I think it'll be good for the writers to get back to the half-hour format.  These two hour specials they've been releasing to DVD haven't been quite as awesome as the original show, and I think it was from trying to stretch their stories to fit the longer format.

I'm definitely looking forward to the revived series!
