Australian promoter Ken West told fasterlouder.com.au that he would be happy with any of the three closing the festival.
"We haven't had that before. So it's the most impossible lineup we've had because if you think about it logically there's no other place in the world where you'd get these three acts on the same bill unless it was Live Aid," he said.
"That's the only other time you can get the egos pushed out of the way."
Pearl Jam are guaranteed crowdpleasers, with the grunge survivalists selling out Mt Smart stadium in 2009 and leading fans on singalongs through their canon of hits like Alive, Jeremy and Black that date back to the early '90s.
West said Pearl Jam were naturally "very cautious" about headlining festivals, following the deaths of nine people and 30 other injuries during the Roskilde Festival in Denmark in 2000.
Blur have visited only once, in November, 1997, on the back of their self-titled fifth album and their well-known anthem Song 2. They split in 2003, reformed in 2008 and have performed sporadically since then.
But the big question hanging over the headliners is which Snoop will turn up: Snoop Dogg, the iconic gangsta rapper with hits like Gin and Juice and What's My Name? from the early '90s, or Snoop Lion, the recently reformed reggae singer who released an album that included a duet with Miley Cyrus.
He is billed on the line-up as "Snoop Dogg aka Snoop Lion," suggesting fans might hear both sides of Calvin Broadus' career. He last played in New Zealand in 2006.
Arcade Fire are also likely to be a major drawcard, with their rousing singalongs and carnival-style intensity proving to be one of the highlights of the 2008 event. They have a new album due out by the end of the year.
West called it "the best lineup we've ever put together" and told fasterlouder: "You have no idea how hard this process has been."
"It's been a very, very long road to get to this point and not in our wildest imagination did we think that they'd all hit at the same time."
Earlier this year it was announced the Big Day Out was returning to New Zealand after poor ticket sales marred the 2012 event - headlined by Soundgarden - and saw the New Zealand leg of the festival canned this year.
In 2014 it is shifting from Mt Smart Stadium to the higher capacity of 50,000 at Western Springs Stadium and tickets cost $185, with the first 10,000 going on sale at $165.
Tickets go on sale on August 12 at 9am.
