On the Rolling Stone website this week, Roger Waters is interviewed, talking about his hopes and fears regarding the future of the Middle East and America, his thoughts on Barack Obama, and has some interesting insights into the 2012 Wall shows...and possibly beyond.

On the shows in South America, in places that don't have arenas, Roger said "I'm playing in soccer stadiums, and I've decided that the arena show that I produced of The Wall is not inclusive enough to play in a soccer stadium. We'd made the wall a lot wider, so I've been working on the content. I've worked on ways that the audience can see that tiny bloke a long way way without it being the standard, "Let's put up a couple of IMAX screens and they can watch us singing and playing the guitar out of sync."

"I don't know [if this will be the last big tour]. They wanted me to go back to Europe after I finish this August and I've said, "No, I'm not going to do that." But The Wall is an extraordinarily satisfying piece to perform, so it may well be that I go back to Europe in 2013. I have no idea whether it's the last big tour. I just don't know."
