Microsoft hints at IE8 improvements?

According to Ars Technica, Microsoft has hinted at Internet Explorer 8 improvements, in its IE blog.

Ars Technica seemed to divine the IE8 improvements from the order of the IE sessions schedule for Mix 07, Microsoft’s conference for web designers and developers.

There were talks given on RSS, CSS, and AJAX support in IE7 at the conference. Does this mean that's where Microsoft is focussing its efforts in IE8? Perhaps.
