The G-Living Network wrote about a new prefab concept, the Habode:

Habode homes are environmentally responsible pre-fab buildings that are tailored to your specifications. All of the houses are the same size (80 square meters), but the floor plan, window placement and doors are all up to you.

Treehugger covered an historic prefab from 1937:

...integrated furniture and appliances, transformer beds, five hundred bucks (about $15 PSF)- what's not to love?

I discovered a blog that's been around for a bit, but that doesn't get updated often: Modern Modular House. A recent entry has me excited for the release of the book Modular Architecture Manual.

The Good Human's Prefab Wednesday mentioned the Modern Cabana:

The structures are also easily expanded, so you can combine different Cabana’s to make whatever size you need, which is pretty cool.

Inhabitat's Prefab Friday discussed French prefab La Maison de Demain.
