OK, ROPENI, that's your "heartfelt believe"... Just some observations...
(A) "Their last album a commercial flop"
With respect, if you consider as "a commercial flop" an album that sells 3 million copies worldwide (2.6 for the time being), NOWADAYS, sorry, you must be an ignorant. If that's a reason to guit, then should quit 80-90% of the rock bands of the world and many other famous artists. Look at the global sales. ABB sells much, much better than the last albums of Prince, Placebo, Strokes, Simple Minds, Massive Attack, Flaming Lips. If i remember correctly, better than the last White Stripes album. Similar to Franz Ferdinard and Arctic Monkeys albums. Talking about rock bands, actually only Green Day ("American Idiot"), Coldplay, U2, Nickelback, Killers and a few more outsell the Stones worldwide, these days. Do you think 20 or 25 years ago less rock acts were able to outsell them?

"Keith is hardly playing"
Realy? When? Where? Was this your conclusion from the show in Puerto Rico?? If i remember correctly, no. Is your conclusion coming from the boots? Then my ears and your ears tell different things.
(C) "Charlie with cancer although in remmision it could come back at any time"
Maybe you're right, maybe you're wrong. But we are not doctors. Health and age will probably be the main reason to quit, but not necessarily in 2006.
(D) "The band not selling many tickets on their European tour".
I guess you remember the same discussion about the "poor and slow ticket sales" in the USA. And finally what happend? With a few exeptions the venues were packed. Exactly the same talk...
