Uche Ogbuji has set up the XPath-ng mailing list for discussing something to follow XPath 1.0.
Yes, the W3C does have XPath 2.0 in progress, but there is the general opinion that it's overblown and too dependent upon other specs, particularly XML Schema.
XPath 1.0 rocks because it so closely follows the 80/20 rule. XPath 2.0 from the W3C looks significantly less enlightened.
As the project lead for jaxen, I'm following the XPath-ng conversations closely.
