OnLive has "emerged from seven years of stealth development" to unveil the OnLive Game Service and OnLive MicroConsole.

The service offers games streaming over the Internet to either an OnLive set-top-box-style console or to your existing PC or Mac.

Here are the official pics, or renders, of the new hardware, as well as some screenshots from the forthcoming service.

Not due to market until winter 2009, we'll keep you posted on OnLive developments in the meantime.
