Microsoft presented the first beta of internet Explorer 9.
What das it mean for Webmaps?
Direct2D will speed up map rendering:

opensource map:

(webkit is good on that)
Hardware accelerated SVG will allow to use vectorgraphics as map overlay.

It is not a beta, but a developer platform preview release - one every 2 months prior to the actual beta builds. It won't work on XP, so no improvement in standards for the current majority user base. If only M$ had started in 2004.
