One of the best sites that I have seen for emerging technologies is http://envisioningtech.com/
There are two interactive graphics on the site with links to a range of new resources. The first graphic provides a vision of the emerging technologies in education.
The second interactive graphic is a glimpse into the emerging technologies predicted from 2012 to 2040.
Plan on enjoying a few hours browsing the Envisioning emerging technologies site and the sites hot-linked to both graphics.
