AC/DC have hinted that they may return to the road in 2013 to mark their 40th anniversary.
Singer Brian Johnson told Pop Eater that the group expected to meet shortly to discussing “how we're feeling” about celebrating the landmark.
The band are also expected to record a new album for their 40th year.
"We never ever say 'we're going in the studio January next year,' if you do that you're straight under pressure and we've never worked like that,” Johnson said.
But the singer admitted that the tour would not be as long as their recent Black Ice World tour, which lasted two years.
