From what I've read, the studio was supposed to be shut down, but Disney decided to finish up what was already in production at the time of that announcement (this, and Yellow Submarine). Then, it's supposed to shut down for good, after those two movies are finished.
...or, again; so I've read. Things may have changed, but that seems very doubtful now. Mars Needs Moms is bombing so hard, they might decide to just can Yellow Submarine and be done with it.
