Robert Plant says he's open for one
As someone (and I am sure I am not alone here), who has followed Robert Plant's love-hate relationship with Zeppelin over the years, that is not what he said. If you look at the article, he doesn't say "Yes, I will do a Zeppelin reunion tour in 2014." He said he wasn't the only one to blame for the inactivity and that he wasn't doing anything in 2014. With Plant, that is far from a firm commitment!
Over the years he has intentionally spoken with ambiguity and has thrown around little teasers here and there that only served to rile up the masses. Until I hear it actually announced (and possibly until the first note is played), I will hold some skepticism.
With all that having been said, I REALLY want to see this happen!
