I'm new to this new site--but I don't see where another "last tour" will make THAT much of a dfference. Frankly, I'm a little tired of aged rock stars pulling it together for one last buck (the horse-kind).
I saw them in Keezar and Oakland--backstage for the last--both a blast--in very different ways, of course...
I like that Plant has gone on to other pastures to sample the grazing--why the hell not?
That said, I doubt very much I could resist a ticket (as I did with the Stones' "Final Final Final tour") if they came my way again.
