Dave Grohl has suggested that the band may take a "long break".

Foo Fighters frontman Dave Grohl has speculated the band may take a break from the music world after playing the biggest gigs of their careers.
The band will play to packed out crowds of 170,000 fans at Wembley Stadium on June 6th and 7th, with members of rock legends Led Zeppelin joining them on stage on the second night.
However, Grohl told BBC Radio 1's Chris Moyles: "We've never really taken a long break, I think it's time.
"We're over in the UK every year, every summer so I think it's time to take a break and come back over when people really miss us."
The rocker added that he thinks the Foos should not play Wembley for the next ten years, after playing a string of huge UK gigs over the past three years.
Additionally, the former Nirvana star said fans should not anticipate a new album being released any time soon.
Last month, NME reported that rumours of a secret Foo Fighters set at the Reading Festival caused chaos as 3,000 fans turned up to small stage believing The FF'ers were really Grohl and his bandmates.
