Just found this article out there:

Looks like Microsoft will be making a hard push in IE9 to support HTML5 over flash, and try to comply with the ACID3 tests. Should be interesting. All I can say is that, from a web developer standpoint, I'm really happy that the latest versions of IE, Firefox, Opera etc are now to the point that I don't feel like I have to create 2 versions of everything (HTML, CSS, Javascript) when I create new sites.
The future looks promising!
