"In current implementations as of August 2012, no popular user agent pre-fetches resources that are subject to media queries until those media queries are satisfied. However, it seems like a more intelligent approach could be taken based on the liklihood that the media query may be satisfied at some point after a page has loaded. "

A "webfont" is a set of resources, not just a single download. A single resource that includes all stylistic variants, which we may not need, plus all the characters, which may go unused, would simply be too large - tens of megabytes for a font with good unicode and stylistic coverage!
