Well, that was quick

Outpost Gallifrey: New Doctor Who Series News Page
The good news: after airing only one episode, the BBC has confirmed the new "Doctor Who" has been picked up for a second season.

The bad news: the BBC also confirms Christopher Eccleston will NOT be returning after season one ends. This makes his tenure in the role the second-shortest, behind Paul McGann who only appeared on-screen once in the 1996 TV movie (but did lend his voice to several audio productions).

The BBC says they are in talks with someone I've never heard of named David Tenant to become the 10th Doctor.
