Well, from what I've HEARD about W13 being destroyed... My theory is that an artifact is going to be involved in it's reconstruction. A friend of mine insists that they are going to travel back in time to ensure that it will never have been blown up. But, I doubt that... And we can't exactly say that H.G. Well's claim about time travel is improbable, considering she was a villain and that they HAVE traveled back in time in Eureka, which is directly part of the W13 universe. Also, the new episode is called the gift, or something to that effect, so who knows?
