Yeah I too do not even want to think about them retiring- for me, anyway, part of it comes from the fact that I don't want to admit to or give in to the fact that I too am getting older and the Eagles have really been in my life since the 1970's-- thinking that was 40 some years ago is so weird because it feels like it was last week.
As Soda mentioned about Fleetwood Mac, I think the Eagles may not do a whole album but may release a few new songs in time to come.
