any more to come?

I have been watching this one faithfully and enjoying it very much. But I saw that "Luther" has now got a role on "Jonas Brothers," which I'm not especially excited about (I watched one episode because it had Emma Roberts, who was on screen for only a matter of seconds. Big whoopi!). "Zeke" has a major role in the new big-screen film "Ramona and Beezus." And now "Ginger" has a recurring role on "Good Luck Charlie." Does this mean they have all moved on? I do so hope there will be many more seasons to come.
