Given that there was never any official announcement of the tour, barring the March 1st Miami show, I don't see how this can alter anyone's plans.
I was hoping to go to Ireland in late June to see U2 and then possibly get my friend's son in France thereafter (as he summers in the U.S.). But if that doesn't happen, so be it. I can wait.
This is especially true as the shows in Ireland (or anywhere else, other than Miami) were never confirmed or announced. All we had was a lot of speculation.
I just saved up a few extra vacation days so I have them for this year's tour.
And now to save up $$. LOL! So whenever the tour starts, I hope to be ready.
But regarding this news... I have to agree with the doubters. How can an illness occurring now cause a delay for March 1st? And how could this illness then mean everyone is suddenly ready on March 28th? I know Bono plays God, but does even he have this power to control when a person will recover?
Some speculation (on my part) is that this is more of a "cosmetic" illness. Some light surgery perhaps? Something that will heal by late March? After all, the sources were very open about Bono's father. Why the sudden cryptic statements about "illness to a family member" now? Or, could U2 simply need more time? They were less than 2 months away from the start of a world tour. Perhaps the illness excuse sounded a lot better than "oh, we need more time".
Just tossing out ideas...
