About web standards:
* The target for CSS support in IE8 is full and complete support for CSS2.1.
* The only CSS3 module in IE8 is writing-mode (for vertical text support). IE has supported this since version 5.x, so it will continue to do so.
* IE8 will not support CSS' border-radius, which is often used to make rounded corners without images. Microsoft's Chris Wilson confirms that border-radius support is "high on the wish list," though, and should make its way into the next release after IE8.
* There is no official roadmap for IE9, but native SVG support is likely.
