Yes we need it…

Nick Santora hints that the writers would stay around as long as the network asks, even though everyone says that Prison Break Season 4 will be the last.
“We will continue to make PB for as long as the network asks us to,” Nick writes on PBreakFans. “But if we are not asked back for a 5th season or a 6th or whatever, that would be the end of the road. But we, as writer/producers, don’t worry about that stuff — we make as good a show as we can and see what happens. The network has been great to us and they are our partners in the show — we will work hard for them and give them a show we hope they are proud of and see what happens. That’s the way it is on every show. You put it on the air and hope for the best.“
