I think a hiatus is coming but what we have no clue is what will happen for real I can see them still working again as solo so I think for the fans there will probably won't be any real hiatus (after These days both jon and richie had their solo and the fans where busy only 1999 was really off)

I am sure they will stop as a band for a while but not as individual so the *we need a rest* concept doesn't have much meaning beside the need the have to NOT BE TOGETHER for a while

I could bet Jon will work like always
It was IMO a bad move for the band health to have such a intense tour in 2010 and 2011 but maybe they needed that to understand *enough is enough* meaning
