The Guardian sat down with Dan Aykroyd, who dished more on Ghostbusters 3, currently being developed at Columbia Pictures. Here's what he had to say:

"A period piece, it takes place two years after the events of the second movie and sees Manhattan once again under threat. It's closer in scale to Aykroyd's original vision but in canon terms, it's the next chapter of the story.

And now for the supernatural bit: after coming together for the game, all the players have stated their intentions to go back, and a script is being written by Gene Stupnitsky and Lee Eisenberg, writers on the US Office.

According to reports the original cast will act as mentors, handing the company over to a new generation, likely to be from the Seth Rogen and Steve Carell class of actors who are filling up just the same space in Hollywood as Aykroyd and Murray once did. "There'll be a whole new generation that has to be trained and a leader that you'll all love when you meet her," says Aykroyd. "There'll be lots of cadets, boys and girls who'll be learning how to use the neuron splitter and the inter-planet interceptor - new tools to enable them to slip from dimension to dimension."
