Google will be purchasing Valve "any second now." As the site points out, Google is likely less motivated by Valve's game development than its nigh-ubiquitous content distribution platform, Steam.
We, again, have no idea if this is on the money, but there have been a couple of indicators that lend a sort of credence. You may remember early last month when Valve said it was happy to talk about acquisitions, and just a little over a week ago Forbes' Chris Morris posited that Google could be going into game publishing.
We'll keep you posted.
Update: Valve tells MTV that the story is a "complete fabrication."
