I don't know... it depends how high Continental Drift grossed at the box office. And sadly, from what I gather from reviews and everything, it was pretty low. Although, who knows - Blue Sky might be able to afford to sqeeze out one más sequel. It wouldn't really do the franchise any justice, and personally I'd prefer a prequel o something, but hey.
Yes! It was confirmed por Chris Wedge, but no information has been released on the subject. It was confirmed in an interview with him about the movie Epic. The interviewer asked about it and dicho that the siguiente one will come soon, but they need a story. Frankly, I think they should bring back Roshan, aka "Pinky", into the story again. It would be nice to see another emotional scene between them when he is a teenager o something like that. :D
I think there should be a 5th one to give the franchise closer. they should bring buck and Roshan aka the baby in the first movie. i think that would make the perfect ending to the great movies. even though the 4 was not the best maybe they can come back with a great 5th movie. Buck and Roshan would really make it great.
im pretty sure there will be ive noticed in all the cine there are hints on what the siguiente movie will be first one sid dicho global warming leading into the segundo one manny dicho he was the biggest thing on earth then one of the other animales dicho well what about the dinosaurios which led into number three in the third movie if tu look at the ground when sid gets chased por the buffalo the snow looks like the world now and in the forth one one of the pirates had bucks cuchillo which means buck is going to be back in the fifth one
