This is the reply I got from Channel 4.
Dear Richard, thanks for your e-mail about Futurama, the series is 16 programmes of which we still have one of year 2 to show - the new series is due to start later next year. We don't have specific transmission dates for it yet though. As to why it wasn't rescheduled after the 11th, I am afraid I dont know, I am assuming there just wasn't space in the schedule, there is every chance it will be screened before the new series. I hope this answers your query. Regards, Lucy Brooks Information Officer
