Recent rumors seem to point to Australia in February, South America in March/April. So if this holds true, tickets would likely go onsale around the September/October timeframe. My feeling is that once we get through August, the puzzle will start piecing together in September.
When madonna was in australia in march earlier this year someone asked guy osery when u2 would be in australia and he said same time next year meaning march 2017.

One of the big aussie tour promotors Michael Gudinski has said that there will be a march and april full of great rock in 2017. The rumours are bruce sprinsteen is coming but maybe u2 might be also?
