Welcome to PEEL, Charleboss. Enjoy it here.
The fact that FOX still haven't renewed Futurama for a fifth season, isn't the same as it being cancelled. Thanks to the ever amazing planing skills and intelligence (or lack of ditto) of the FOX execs they're stocked up pretty good on episodes. They still has a few 3ACV episodes, and almost all of the 4ACV batch left. My guess is they'll hold out a bit longer before acting.
Why they're doing it this way is beyond me, but FOX execs acts in mysterious ways.
