In an interview with Rolling Stone, frontman Bono
Although the singer said he'd be content with ending U2 in 2011 ("We'd be very pleased to end on No Line on the Horizon"), he also doubted that the band would actually stop. Bono said that working on the deluxe Achtung project has helped light the band's way to a possible future. "Ironically, being forced to look back at this period reminds me of how we might re-emerge for the next phase," Bono said. "And that doesn't mean that you have to wear some mad welder's goggles or dress up in women's clothing. Reinvention is much deeper than that."
