Is U2 Done Touring Forever?!?! Is the Band Breaking Up??

Last night was U2's final performance in their concert tour.  It had been postponed because Bono was dealing with losing his voice a few months ago.   But last night U2 was in top form.   However, the band ended their concert with an intriguing choice of words.  “We’ve been on the road for quite some time,” Bono told the crowd, “just going on 40 years, and this last four years have been really something very special for us.” What really raised some eyebrows was his final comment: “We’re going away now…”  So what exactly does that mean?  Is the band retiring from touring??  Are they breaking up?  No one really knows for sure.  Some people are taking it to mean Bono just can't handle touring anymore so this last tour was it.  Others are fearful the band as a whole is done completely.  It's hard to know what Bono meant by that statement, but I'm more apt to think he meant done with touring but not done with the band.  What do you think he meant??
