Word on the street (original source) is that Windows Vista beta 2, which was slated for a December 7th release, is being pushed to January or February next year. The public release of Internet Explorer 7 beta 2, the first release of the new browser to be available to the Web development public, was slated to be tied to Vista beta 2, so this news may well mean that we won’t get a good look at the many CSS rendering fixes in the browser for another few months at least.

我的意思是干脆取消算了，：）
