But… they made it to New York in the third movie…

Really, I'd be disappointed if they made new Madagascar movies. It ended pretty well, all things considered.

They're gonna have to come up with something really interesting for the fourth one then since, as Icecane said, the series seemed to wrap up well as a trilogy. No qualms about the Penguins of Madagascar spin-off movie though, since I wanted to see them get their own film as far back as seeing the first movie (the TV series was good, but a movie will allow them to have higher quality animation of course, since it doesn't have the same budget restrictions).
