The New York Times is running an article today on multiverse theories at http://www.nytimes.com/2002/10/29/science/space/29COSM.html.
It mostly describes the controversies over the anthropic principle and how the AP works a little better in the context of multiverse theories. The big issue is whether the "theory of everything" - string theory or whatever - will fully specify the universe, or whether it will just describe a family of universes where the AP must then be invoked to explain why we live in the one we do. There is also a related, brief article at http://www.nytimes.com/2002/10/29/science/space/29MULT.html about how different theories lead to multiple universes. However neither article goes so far as to seriously discuss the all-universe model. The first article also has a link to a really nice animation showing an inflation-style multiverse model.
