All the interior sets were stripped out right?

Nope. The sets were in storage until the end of this year according to a producer.

Coincidentally at least one tabloid was running an article yesterday online showing photos of the interior sets still in place/storage.

I think the bigger question and potential issue is how many of the cast wish to return? I seem to recall Ryan Moloney (aka Toadie) previously saying in interviews prior to the (then) final episode that he had been planning to leave the show. I imagine that some of the actors may have already found other work prior to today's announcement.

Presumably when the break from being on screen will allow the writers to come up with reasons why some of the cast have moved away from Ramsey Street in the past few months. However, the more that decide not to return the harder it is for those reasons to sound believable onscreen.
