Season 4 is still possible. Do not deny it. If you are a true Suite Life fan, you will agree with me. It has not been confirmed or denied that there will be a season 4. The Sprouse Bros. are not going to college for another year, so it is still possible. The actors all still want to do the show. So, stop denying a season 4 until anything is confirmed!
I still have no idea if there will be a season 4 or not. Nothing has been announced yet. I think Disney is just waiting to see how many viewers tune in to Prom Night, The Suite Life Movie, and Graduation on Deck. The cast still has no idea either. That means everyone needs to watch all three of these. We need as many viewers as possible if we want a season 4. If I hear any more news about a potential season 4, I will let you guys know!
It has been confirmed that season 3 was the final season. Sorry everyone, I wish it wasn't the last season, but it is.
