Alright, for those who believes the world will end by that year, you’ll probably figure out that Microsoft is the cause xD.
Anyway, according to Tech Radar, Windows 8 will be out in 2012. I can’t remember where I read that it’s Microsoft “Biggest risk since it’s start”. But if that’s true, I’d like to imagine they’re going to OpenSource it… I know that’s a dream. But hey, I like dreaming xD
You’ll find better details and what would you expect from Windows 8 in the Sourced link.
