Not that I want to put this up, but I do have to answer the question with the information I know. Please don't shoot the messenger.
James Patrick Stuart commented on Facebook back in September that the final Penguins of Madagascar episode had been recorded. Candlefairy_13 put up a screenshot this several months ago: link

Thanks, SJF. It's good to know weather the show is going to end at all or not. This gives us the answer, even though it's not the one most would want to hear.
I remember Bob Schooly posting on his Twitter account "penguins is done, maybe next show" or something like that.
However, things can be subject to change. Historically speaking, due to a large letter-writing campaign, Star Trek (back in the day where your parents were fans of a TV show) got an extra season and was pulled out of cancellation. And you could still see it on some channels today.

Star Trek: The Original Series WAS a pretty epic show. XP
