Disney's Suite Life On Deck "Graduation"?

I just watched the most recent suite life episode moments ago. They (7 sea's high) class have graduated and will continue out their lives..... however will they be a possible spin-off , because of the show being so successful between that and disney's hannah montana , suite life began in 2005-2011 (6 straight years) i have not looked completely into the suite life future for the show but is their any information on a possible take off from high school on the boat? Or possibly an idea of what they may do with any idea of continuing the show with ethier dylan or cole sprouse ? any kind or answeres , opinons, ideas, or facts are welcome , thxs !!!!!
