When Joe said, earlier this year, that the Eagles had new tracks done, I just assumed that they had wrapped up the unfinished Long Road Out Of Eden tracks, to be included as extra tracks on a near future compilation.
As we approach the end of 2014, I'm sure the Eagles will be under pressure to release anniversary editions of their two monster sellers, Greatest Hits and Hotel California in 2015 and 2016. The fact that there are no unreleased rarities in the vaults isn't much of a obstacle.
They've spent the last few years performing every track from Greatest Hits so they could easily re-release it with a disc of recent live recordings.
The Felder issue could prevent revisiting Hotel California in 2016 but I'm sure they could cobble something together.
2017 is then the 10th anniversary of Long Road Out Of Eden, which would be an ideal opportunity to release those new tracks, Joe mentioned.
I believe the unreleased tracks were finished instrumentally but were just awaiting lyrics so the vocals could be worked on. They've had ample time, since to do that. So it's just a matter of how they'll be released.
It'd be great to have a brand new Eagles album to follow Long Road Out Of Eden but after 7 years, I'll be quite happy with a reissue or compilation, as long as there is some new material on it (but not, One Of These Nights part 1, or Born To Boogie rubbish).
