I think it's pretty odd for this to have gone on so long when we all know that they're going to wait. They are in it for the maximum return and that means Stevie Nicks on an album of Fleetwood Mac material. Whether we feel they should release whatever they have now or wait, it doesn't matter.
I look forward to whatever they release whenever they release it. And as soon as I find a reasonably priced ticket I'll be counting down to my first show with all 5 Rumours era members onstage.
