From the article:
More specifically, this means adhering to the latest web standards, such as HTML 5 and CSS3 Selectors. At the keynote, there was a demo with CSS-based rounded corners in an element border. That's very specific, of course, but it's something that IE 8 doesn't do properly today. The current, very early IE 9 version correctly utilizes 41 of the 43 CSS Selectors and scores 574 out of 578 in its CSS3 Selectors test, a big improvement over IE8, which scored 330 out of 578.
