TBH, no one really knows. I'm sure they'd like to. They haven't been there since 2003, I think? So that would make it the most major part of the world that they haven't been to in quite a while.
If I had to engage in wildly unfounded speculation, I'd say that they'd probably like to find a way to make it down there this year. There are most likely more tour dates to come this year. With a few exceptions,
http://www.underworldlive.com/events seems to have the most up-to-date tour dates announced first, so keep an eye out there. In fact, there seems to be a new Ireland date that no one has mentioned yet.
