I have to wonder how that's even stable. There must be some interesting orbital resonances involved, assuming that it is stable.

They'll have to track that one for a while, getting a really good data set over a fairly long period of time. Just how long they'll have to do that is problematical, but I'd say at least 10 years. It may be that the big gas giant so far from the main star was captured from another system or something of the sort -- I'd love to find out what makes that system the way it is.
