No we were not "close" to anything and the album has not been "delayed". There was never an official date announced, it has all been pure speculation so far.
All this crying over one silly magazine article. It's not like we have an official statement of anyone from the band or management and I'm pretty sure we won't get any because it's also based on rumors.
We have statements from band members, one very strong from Bono from only a couple of days ago, and nothing is hinting towards a 2015 release. It's ridiculous to freak out like that now.
But yes, IF true, that probably means: Starting from scratch. They don't postpone an album for another year if they have half of it ready as Edge said. And 30 songs or two albums planned as Bono said. Something's very foul here.
The Billboard article doesn't reveal much, it's mere speculation and a summary of what's been happening in the last months. No direct quotes, no interviews, no official statements.
