Having announced that there won't be a 2010 tour, it makes all the sense that the Stones next big effort will be late 2011. CD, Tour, DVD, Live Album, etc...As 2012 marks their 50th aniversary, They also need to put a bigger gap between tours in order to get the interest back. (not talking about the crowd here).
Let's hope that Fifty Licks has Don't Stop, Stealing My Heart, Keys To Your Love and Losing My Touch because those were sure signs that the Stones were still moving forward in their fourtieth year and they MUST be hits cause they're...on a...career spanning....hits comp.
According to Wikipedia Honeyboy" Edwards (age 94), and Pinetop Perkins (age 96) are the oldest and, arguably, the last Delta blues players still touring. They both do about a 100 shows a year.
