IE8 will pass Acid2
Yep, I thought that would get your attention
Microsoft have announced the following about Internet Explorer 8:
Microsoft are targeting 1H08 (first half of 2008) to deliver IE8 beta 1.
IE8 in standards mode now correctly renders the Acid2 Browser Test. For compatibility purposes IE8’s rendering engine will default to “quirks” or “standards” mode. Site developers will need to insert a new opt-in flag to request the page to render using “IE8 standards mode.” Websites that are coded for previous versions of IE will behave in exactly the same way in IE8 unless the website authors opt-in to IE8 standards mode by placing a simple tag at the head of their HTML document.
IE8 will include "a number of innovative and beneficial features for enterprises, consumers and partners " - details to come.
