Microsoft made their own IE6-countdown site.
Interesting... if you get rid of China and S. Korea, IE6 is probably less then 5%.  I think IE6 is close to becoming a footnote.  With IE9 not supporting XP, I'd love to see MS recommend FF4 or Chrome for XP users, although frankly I don't think it would matter... if you're still on XP a modern web browser is the last thing on your mind.
