GO: Google's programing language

Today Google announced the release of a new programming language called GO. The reason Google mentions to release this new language is that the rest of the languages are starting to get dated. Current languages are not designed with multiple CPU's, massive clusters, client/server, sprawling libraries and dependency chains in mind. After the release of Google Wave (Communications) and now GO the big thing Google is not operating in is the desktop OS segment. I'm curious when and how this is going to happen.
