And I honestly don't think that Mick appearing on a TV show, or Stevie doing a benefit concert here and there is what's slowing down the release. I'd rather they take all the time they need, and give us a kick-ass album, rather than rush everything just to please the impatient fans.
As far as timing, there are basically 2 times a year that record companies saturate the market - spring and Christmas. Peak touring season is spring thru fall, which makes sense, considering the logistics of touring, avoiding winter weather, etc.
Just my 2 cents.
